Well, that doesn't say at what point your order is registered, as in when is your name on a set of brakes. 

If you need to receive payment info on email, and open that. Then type in all that info into an app, and then transfer the money and get a confirmation on that transfer, then how can all of that take 10 seconds...

The important part here is only to spend as little time possible to register an order. What app or payment option you use to transfer the money is irrelevant. 

 

So, at what point in the order process is your order locked in?

you asked to correct you if wrong. i didn't correct you. the moment you hit "buy" the brakes in basket are yours. not when you finally paid. i paid mine like a full month later. you just have all your infos in before the drop and then react fast by adding the product to your basket.

Ok, good to know. 

Personally I'm going for Hope Tech 4 V4 this time. I've been back and forth between brands for a while, but so far I just like the ecosystem of Hope in general and are willing to give them a try.

I'm sure the Intend Trinity are awesome and all of that, but what do you do when you need parts in the middle of a season. If I could afford two complete sets of brakes so I had a backup, it would make things easier. I'm just going to make a clean pass on them for now, and hopefully certain things will make them easier to own after some time. 

I like companies that make a complete parts diagram for the customer to look through in his/her own time, and with part numbers and everything, because you can do all the research in advance which save you and them a lot of time. The best thing is being a customer and not needing to contact them at all. Just find what you are in need of, where you can obtain that thing and just drop and order when you wish to do so. 

Hope does that well.

On Hope vs Intend, I've had both and they feel very different. Personally, I like the Hope lever mounting a lot better than Intend and they don't have issues with the lever blade being too short for wider grips. The power is similar but the lever feel is really different, the Hopes are closer to Trickstuff in the sense you don't get a ton of feedback at the lever when the pads engage, but the power comes on faster and the adjustments are more meaningful. The Intends have a really light, nice feeling lever - but it feels more like Dominions in the sense that as the pads engage, the pressure at the lever builds more. The Hopes can actually be a little disorienting and the first ride on them I did, I nearly ate a stem sandwich due to putting too much brake down expecting that lever pressure to build more than it did. They are wonderful feeling brakes though and I like them a lot. The only real con to me is the bleed process, which I'm just not a fan of at all. 

I prefer the Intends but that's not a knock on the Hopes, I just prefer the overall maintenance/support from them as opposed to Hope, but both are top tier of those I tried. 

On ordering, I did effectively what Pedal Bob suggested twice now successfully. You will save critical moments having multiple tabs opened and putting your checkout in another window. The site gets hammered about 1-2min before they go live, so having several windows open at once helps a lot when it comes to avoiding extra clicks/buttons. Having autofill ready to go and signed into PayPal helps, too.

I've tried neither, so I'm just at a crossroads where I just have to try something new and be open to adapting to new output. I'm just done with Shimano brakes, so I'm sure I can learn to like a different lever feel. How and what and all of that will have to wait. 

Still snow here, so got to order some parts and assemble the bike for season start.

Hope v4's are the best of all the brakes I've tried, which is pretty much all them now. They'd be a 10/10 if you didn't have to fluff around with the resi lid when bleeding. Worth a shot!

I'll pre-empt the inevitable butthurt about the below by saying that all of these options are good. They are all powerful, all reasonably easy enough to work on, and all (mostly) consistent. I mainly say that because people adore Saints and I found them to be the weaker in almost every category compared to others, but still good. 

I'd also caveat that "power" is somewhat misunderstood IMO. Most people don't have the means to measure overall, total available power, rather they base it on how the brakes feel. A brake like the Maximas may have a ton of overall power, but the Mavens feel more powerful because the power comes on sooner as the brake ramps up. This will also be relative to your weight and how you want the levers to feel.

I posted something similar in another thread, but I'll go into more detail. For reference, I'm 220lbs on a ~33lb steel 29er.

Power: Maven >= Radic > Intend > Maxima > Hope T4 V4 > Dominion > MT7 > Saint - The Mavens have a very quick power deliver,y once the pads engage the difference between "I'm slowing down" and "I'm skidding" is miniscule. This can be dialed in with contact point adjust, but they apply power more progressively than any other brake I've tried. The Radics have a really similar feel with a lighter lever, but feel a bit more controlled and have less deadstroke, basically instant engagement, I ran these closer to the bar than any other brake. The Intends are very close to that feel, but with a much lighter feeling lever and overall better feel, although they lack contact adjust so you can't tweak them as easily. Both Maximas and T4 V4s have enormous power available, but it comes on later in the stroke and is harder to define in lever feel and requires a longer lever throw to obtain. They are the epitome of having a smooth, light, powerful brake that requires a longer lever stroke to get there. I love Dominions and I loved the MT7s, but the power comes on later especially with the latter. I didn't find Saints to be as powerful but they are good enough. 

Consistency: Basically all of the above were consistent with two exceptions. I have been able to fade Dominions on long, flowy descents. I've torched them more than a few times with no change in lever feel, but I've had them turn mushy a few times and that's not an issue I had with most of the others. On the Saints, I had the wandering bite point problems I had with every other Shimano brake, but only in cold and I think this is, in part, due to brake technique where two quick pulls of the lever causes it to change. Some don't have this problem, I did. The rest were very consistent, rarely changed lever feel, and I had no issues in hot/cold or with fade provided they were bled properly. The Mavens did exhibit some wandering bite point (BADLY) when they were new out of the box, but doing the piston massage procedure did away with it. 

Lever feel: (For me and what I'm after) Intend > Radic > Hope > Maxima > Dominion > MT7 > Saint > Maven - The Maven lever feel isn't as bad as people act like it is, but it is firm compared to the others. It's not that it is unusable or awful, just that the other options are smoother and require less force through the deadstroke (I'd argue the engaged force to power is better than some are acting with the Mavens though). I loved the feel of them overall, but the stiffer spring is off putting compared to others. The MT7s were very consistent and smooth, but power came on later than I liked, the first few rides on them I blew a few corners because I kept expecting them to grab faster coming from the Radics. The Hope and Maximas have a lot in common, it's a very light feeling lever even when the pads engage, but it can be somewhat vague if you aren't used to them compared to others, you don't get that 'wall' of sorts you do with other brakes, it is light all the way through and that can take some adjustment. The Radics have a super smooth lever but engage almost immediately with no deadstroke. The Intends are the best of the above, moderate deadstroke, even power delivery, smooth/light lever feel, easy to identify the brake point, and good ergonomics. My preference in this category is a quick power delivery, but lighter riders or those who want a longer lever throw might place Hope or Trickstuff higher.

Aesthetics: They are all nice except the Mavens. They are the ugliest thing on my bike at the moment and I'm dying to get them off. It's very off putting for an otherwise great brake. The Trickstuff, Hope, and Intends are all beautiful in their own unique ways. 

Cockpit: The Mavens suffer from the reservoir sitting too close to the bar. This means controls may not fit where you want because it interferes with the reservoir being so damn close. Otherwise you have a lot of positioning with the lever. The Dominion and MT7 share a lot of similarities in this regard as well, but aren't super notable otherwise, you have plenty of lateral movement across the bar to position them and your controls, although I prefer hinged levers. The Hopes have a super long lever blade that might interfere, but I found that they sat so far inboard it didn't interfere with my other controls. The Radics, Intends, and Maximas all have a lever brace on the reservoir. This is a good thing that prevents flex, BUT it also means that some controls won't sit properly outboard of the clamp due to the lever brace being in the way, this is particularly noticeable on the Radics. The Maximas are generally OK in this regard, but the lever reach adjuster might conflict with controls. The Intends have one possibly fatal flaw I mentioned before: the brace position combined with the usable lever length means using long grips like Meaty Paws positions the lever so far inboard you can't reach it. I have it near slammed against my grips and it's fine, but this may be a problem for people with certain hand sizes. The Saints have a super nice, rigid feeling clamp that I wish others would adopt. The Mavens will flex slightly under heavy power, IMO they should've adopted a stronger clamp, Matchmaker just isn't it.

Install/Bleed/etc: The Intends are the cleanest bleeding brake I've used, they are super easy to bleed and install, I also like that they use a reusable fitting that rotates. The Maximas are more work due to the braided hoses, but are pretty easy if you can cut them properly, they also have instructions for aligning the hoses, which is nice. The bleed process for the Maximas is often complained about but I had no issues, I just followed the instructions and it worked out. They should include the bleed block with the brakes, it's absurd they don't. I had issues with the Hope hose kinking and twisting, but other than that it wasn't noteworthy. The Saints, MT7s, Dominions, were all easy to bleed and install, although I know some report problems with alignment on the MT7s and bleed problems, but I didn't have that issue. The Radics are easy as well once you get used to working with the braided hoses, the Bleeding Edge fitting they use is super nice. Finding Bionol in the US is a nightmare though, for those and Trickstuff. The Dominion bleed block includes a half block on one side you can use to work the pistons out safely and clean them, IMO everyone should do this. Hope provides something similar in the form of a STL file you can 3d print, but not everyone will have access to one to do this.

Value: Overall the Dominions are the best combination of everything IMO, if not the best at any one category, but for the price you get a lot of good stuff that makes them the best value IMO. The Trickstuff are a hard sell at $1200 and I think it's dumb they don't include the bleed kit, block, and especially fluid given how hard it is to find. The Intends I feel are a good value considering everything they come with and their performance, but they are hard to obtain and no doubt expensive. Hopes are kindof middling, more expensive than Dominions, but cheaper than the others and offering similar performance/feel. The problem with them is quickly finding parts if you are in the US. You can get MT7s very cheap these days, but I'd still opt for Dominions over them given the other factors. 

If you like running levers close to the bar and want a ton of power, get the Radics, there is no better option with such a short deadstroke to power point. If you want a long, linear, smooth pull with gradual power delivery, Hope T4 V4 or Maximas will get you there, with the Maximas being slightly more complicated to work on and harder to find parts for (this may be a major issue down the line and is my #1 concern with anything Trickstuff). If you want rapid power delivery, the Mavens, Radics, or Intends all fall into that category (in that order), the Mavens require more throw than the Radics but power comes on faster once the pads engage. Overall for most people I usually suggest the Dominions, they are a good average point despite not being the best at everything, they are good at everything and lack the pitfalls of some of the others. For very heavy riders, Mavens or Radics would be my choice. Lighter riders would get along better with the Hopes, Maximas, Dominions, and possibly MT7s. The Intends are a slightly more powerful, easier to work, and refined Dominion, so if you can get them and don't fall into one extreme or the other in how you want them to feel or weight range, they are amazing.

I haven't tried TRP, Beringer, or that brand that's a number (I forget what it is).

With such concise experience of all the best HD 4 piston brakes, your experience on the HEL Advocate would be much appreciated!

Based on your extensive writeup, it's between Radic and Trinity for me thus far.

Thanks

I haven't had a chance to try those, the Br4ve, or 612s. They all look sweet/unique in their own way but I haven't had a chance to feel or use any of them, kinda ran out of steam combined with neuropathy in my arms cutting down riding time significantly.

That's a huge bummer to read. My wife has a few patients she works with, and my dad's life partner has it bad as well. Best of luck with that.

Does anyone on here have experience with both the Tech 4 E4 and the Tech 4 V4?


I’m wondering if the E4s have a less of the kinda vague lever feel that the V4s have. My main gripe with my V4s is how the bite point feels vague/mushy.

i keep reading this and i keep finding my brakes the opposite, V4 braided paired with hope adapters and 2.3mm rotors, so i'm wondering, given that every other Hope brakes i try always have the normal hoses and feels soft/spongy, and mine and some customers that i installed, all with braided hoses, have a nice and defined/firm bite point, what hoses do you have?
While Hope's claim is that there's no difference, i really don't believe it, stiff hoses do make a difference, especially in feel.

I have the standard lines, but I’ve felt the braided lines on a friend’s bike and they feel basically the same to me.

I don't have the Hopes but I have some braided vs standard experience on my Maxima. I had to run a standard rear line on my old bike because the 6mm braided hose wouldn't clear the internal routing. I still kept the braided hose for my front brake. There was a minor bite point feeling difference between the two. The Goodridge hose bite point was more sharp and defined while the rear standard hose was a tiny little bit mushy in comparison. My new bike has external routing so I can finally run the braided hoses and both front and rear brakes now have an identical feel.

From what I had in the shop, not the same at all 

Not sure on the trail as I’ve only ridden on braided hoses with Hopes but even riding with a guy that had the exact same set up other than hoses he said himself that mine felt way better and more defined 

I’d try to bleed the caliper by pushing pistons out and opening the bleed nipple while pushing them back, perhaps there can be some air behind the pistons making them feel more vague, I’d try it, but I’m confident that the stiffer hoses do make a real difference especially on brakes like these pushing strong pressures

Personally I will be going for the braided lines just simply because the price jump is marginal. That said, I have seen they mention that the new version of their braided lines now have the same outer diameter as the standard black hose, so I'm curious if there could be differences between old vs new braided lines as well, to add yet another variable(?) I'm not aware of when the new version hit the market, so I'm only mentioning it since it may be of importance.

On top of that maybe it would be good to bunk/debunk the effect of storing a bike vertical or not in terms of wandering/soft bitepoint, as it seems more and more people store their bikes vertically.

it's a while they're 5mm, mine are for example and the one i got in November for a customer were 5mm as well

Hope v4


Anyone try and fit a slightly longer bite point screw to firm things up? Brakes and perfectly bled and even slightly overfilled and still not as tight as radic/mavens

It’s just a different brake, it won’t get like the other 2 mentioned and it doesn’t matter, on the trail when the bite point is all in they become super touchy and honestly hard to modulate

I actually didn't put a longer screw....it's a damn custom size of course.....but there should absolutely be aftermarket options. What I did is epoxy 2 layers of precisely cut butyl road tire tubes to where the bite point contacts the reservoir. It effectively added 2-3mm? of screw length/bite. I am only running 2.3mm rotors so maybe this is what it's like running the 3.3 vented rotors? 

The vented rotors are hilarious overpriced so not doing that. 

Either way, if any manufacturers are reading this, please machine a longer screw for Hope V4 bite point. HUGE difference.

3.3mm rotor = Less brake fluid

2.3mm rotor = More brake fluid

Both should function the same in regards to the bitepoint screw if the last service was done right. The V4 calipers should even work with 1.8mm rotors according to Hope, so to me it sounds like you either have too little brake fluid in your system and/or it just need a service.

What you describe with lengthening the bite point screw to change the feel of the brakes isn't really consistent with how hope brakes, or open hydraulic brake systems in general, work. 

The bite point screw doesn't change the position of the pads; this is determined by the seals in the caliper and the gap to the disc will be the same for any disc thickness. What the bite point screw does is change the position of the piston in the master cylinder relative to the reservoir bleed port so that more or less lever throw is required before the master cylinder piston passes the port and starts to move the caliper pistons. Once this happens the brake will behave in the same way regardless of the starting position unless there isn't enough fluid in the reservoir and then air will enter the system. This is why Hope recommend adding extra fluid in the V4s when using 1.8 or 2.3 mm discs.

I'm not really sure what is going on with your brakes to make them feel different with the modification you made but I would guess it comes down to the bleed or setup not being perfect. Hope Tech 4s don't have a very firm lever feel compared to others, even with everything setup correctly and the caliper pistons perfectly centered.

What you describe with lengthening the bite point screw to change the feel of the brakes isn't really consistent with how hope brakes, or open hydraulic brake systems in general, work. 

The bite point screw doesn't change the position of the pads; this is determined by the seals in the caliper and the gap to the disc will be the same for any disc thickness. What the bite point screw does is change the position of the piston in the master cylinder relative to the reservoir bleed port so that more or less lever throw is required before the master cylinder piston passes the port and starts to move the caliper pistons. Once this happens the brake will behave in the same way regardless of the starting position unless there isn't enough fluid in the reservoir and then air will enter the system. This is why Hope recommend adding extra fluid in the V4s when using 1.8 or 2.3 mm discs.

I'm not really sure what is going on with your brakes to make them feel different with the modification you made but I would guess it comes down to the bleed or setup not being perfect. Hope Tech 4s don't have a very firm lever feel compared to others, even with everything setup correctly and the caliper pistons perfectly centered.

That sounds weird to me, because that would mean that the bite point control dial is just a second reach adjust. From what I can understand of what you're saying, the bite point control dial is simply adjusting a deadzone buffer before the master cylinder piston starts pushing actual brake fluid. 

My general understanding of hydraulic brakes was that obviously the seals is the first step of determining where the pistons will end up. Adding a bite point control dial would be the second step of giving you some fine tuning, and not only when everything is brand new and fully serviced. 

The lever reach should just be to place the lever where it suits you personally.

That's at least how I've looked at it till now, and obviously I understand there can be different ways of doing things from manufacturer to manufacturer, but I just find it a bit odd if what you claim is actually true that you're only adjusting a deadzone of the master cylinder piston.

I actually didn't put a longer screw....it's a damn custom size of course.....but there should absolutely be aftermarket options. What I did is epoxy 2 layers of precisely cut butyl road tire tubes to where the bite point contacts the reservoir. It effectively added 2-3mm? of screw length/bite. I am only running 2.3mm rotors so maybe this is what it's like running the 3.3 vented rotors? 

The vented rotors are hilarious overpriced so not doing that. 

Either way, if any manufacturers are reading this, please machine a longer screw for Hope V4 bite point. HUGE difference.

All a bite point adjust does is move the MC piston position relative to the timing port holes in the MC. The smaller the gap between the primary seal on the MC piston and those ports creates a shorter throw before engagement. Generally, adjusting it won't alter the lever's home position, with Shimano being an exception in that regard. Shimano requires adjusting reach to maintain the desired home position when their bite point adjust is fiddled with. All that is to say yes, bite point adjust=deadband adjust. If one can't get the activation point they're looking for using that, then there is/are other factors at play, from simple (improper setup at install, bad bleed, kinked brake line, excessively worn pads and/or rotors) to the harder to diagnose (manufacturing dimensional issues within the system, assembly issues at build).

Only thing I would be concerned about here (aside from voiding your warranty) is inadvertently pushing the primary seal on the MC piston past the timing port holes, making the system a closed brake. Time will tell. If you start to lose a brake due to starving the system of fluid or start to have the brake locking up/bite point firming up erratically will tell you that is the case.

For all things mechanic wise, assume you're the weak link in the process and do your best to strengthen your knowledge of fit and process. RTFM, RTFM again, RTFM one more time for good measure. And read it, don't skim (done it, bit me in the ass a couple times, and it was embarrassing). If all that fails, reach out to tech support. The folx working phones and computers are generally hella helpful and quite likely more experienced in the set-up of their wares and definitely know of any potential manufacturing issue that's preventing you from getting the ideal you're looking for. Don't be afraid to be wrong in your thinking either. Sometimes it turns out what you were looking for was not the way a system was designed to operate.

Be curious, be reasonable.
