Does anyone have tips on how to measure the brake caliper vertical alignment so that the brake pads are centered on the friction ring? One method I was thinking was to use a marker on the disc and then observe where the pads make contact.
I’m using Shimano Saint brakes with TRP RS01E 223mm discs. The rear has an IS-PM adapter and the caliper fits very tightly, so it might require some creative thinking. I have couple of Magura shims to align caliper.
I think the question is more along the lines of the diameter ring where the pads contact, not where the pad makes contact with the rotor on the surface area of the pad itself vs. where it does not (that would cover checking if it moves parallel to the rotor or rotates inwards).
For the 'wear ring' method, sharpieing the rotor makes sense.

The Trinity brakes are really really good. I've tried a lot of brakes recently (Code, Saint, MT7, Radic Kaha, Intend, Maxima, Maven, Dominion, Hope T4 V4, a few others I'm probably forgetting) and they are my favorite of the group. I strongly recommend them to anyone interested and willing to pay/run a niche product like that, with the caveats I mentioned above.
They do take a little bit longer to sortof 'bed in' than others. The pads took longer than I was used to for the power to come in, but I also had a minor issue with the pad dragging slightly. After I rode some steeper stuff and got them moving a bit more, that went away. They feel like a more boutique, refined Dominion.
The obvious downside is getting ahold of them.
I am interested to see what Magura does in the near future. They've been liquidating MT7s at heavily discounted rates and I suspect something new is on the horizon. I really liked the feel of the MT7s, but felt the lever body could use some refinement and the initial bite of the pads was a bit lacking compared to similar options.
Just bought the trinity a few weeks ago, didn't have the chance to go on a trail yet but went around town trying to bed in the brakes.
The modulation is amazing, but I still feel there is power left there on a 1 finger pull. Still can't fully lock the front wheel on a fast hard 1 finger pull (unless I use 2, which I never do). Don't need to lock the wheel when I go blasting through a trail, but I want to know I have all that range on 1 finger.
Is this something that shows I still need to bed in the pads more? Using 220 rotors front and rear, 2.3mm monolithic forumlas, 94-96kg average kitted, 16.7kg bike

I weigh more than you and ran these on a bike similarly weighed, you shouldn't have problems locking either front or rear wheels. I would suggest trying to bed them better and re-do your bleed to be certain, getting all the air out can be a bit of a chore the first time. I'd say something is off though b/c locking either front or rear shouldn't take much effort at all.

How many rides have you done on brakes? Mine didn’t take too long to bed in.
You may also want to re-visit your bleed, I had to bleed a few times to get all the air out and now my brakes are solid. There was a good reply to me about this a few pages back.
I can lock the front wheel pretty easily on my setup with 203 2.3mm rotors but Im also only at 75kg rider.

I think you and Primoz are thinkin' too hard, and that's not meant with any holier than thou. The pads will leave a witness mark on the rotor's brake track, even on initial bed in. I'd be cautious introducing anything that may negatively affect pucker power, such as permanent marker.

I can lock the front wheel pretty easily on my setup with 203 2.3mm rotors but Im also only at 75kg rider.
I'd say I did about 20 runs of 30km/h-5km/h braking spurts with a bit of commuting to work and back home through town
I guess I will try a re-bleed eventually if I don't notice any improvement. The free travel on the lever is good and short and don't feel anything spongy after the bite point. Also did the zip tie of the lever close to the handlebar trick.
There is another issue though, when I go do a hard front brake pull on the lever that is very short in duration (about 0.5seconds/less) with instant release afterwards, sometimes it feels like I get dragging pads for another 0.5 seconds when the pistons retract. Sometimes I don't get this issue, they retract instantly, other times it happens like this. Is this a lagging piston issue? I am too much of a novice to figure it out, but now I also feel like there is a different sensation to the hard front brake pull when it initiates, but not sure if this is just in my head.. sometimes I can audibly, clearly hear the pads engage the rotor, other times not (and depending on this, the rotors squeal a bit or howl louder). No idea if this is normal
I did write to Intend and they said to get the brakes hot first and if it doesn't fix it, to contact them again... though I can't really get them HOT in town like on a trail (even after the 20 runs of braking spurts, I still have this happen)

the back is probably at half the bedding process and I can lock the wheel, the modulation is great

What about if you are using used rotors on another set of brakes? There are no witness marks then
If the sharpie will affect the braking power, well, damn, we better cover up those rotors with well sealed covers REAL quick. Think of all the dust, muck and sand getting onto the rotors affecting braking power.

You'd still need to bed the brakes in, which would bring back the witness marks. I look at it as not introducing an unintended consequence. Is perfect* pad depth worth potentially screwin' up a set of pads? But that could be my frugality speaking. Will the solvent and/or resin in the ink mess things up? I don't know, hence my predilection for working with known variables.

Added lever bleed port puts them on my list of brakes to try now.
Im curious to see how it is, it looks to me it’s in a position where air can get trapped underneath the diaphragm, so I’d still bleed them the normal way

After going back and fourth for the last month I decided to pull the trigger on some T4V4’s to replace the Radic Kaha’s that I’ve been running for the last year. I figured my purchase should trigger some event that causes hope to release the new gravity brake causing me to have buyers remorse over the purchase for not waiting, but giving anyone else the opportunity to grab some discounted T4V4’s or the new brake… your welcome 😂.
Some initial impressions:
Last time I worked on a set of hope brakes was at least 15 years ago, and they always seemed to be shelf queens imo. I know that has changed but I’m happy to see/feel it in person. Pad retraction is pretty damn good, having struggled with mt7 for longer than I should have and coming from Kaha’s that are intolerant of any runout in rotors I’m pretty happy that these have a decent amount while still having short throw. Coming to that, the dead stroke is much much better than I was expecting, not sure if it’s exaggerated or what but with the contact point adjuster wound in for the least free/dead stroke I am measuring 14mm until the lever firms up. That’s actually very close to where I have the free stroke set on my Kaha’s, also adjustable, to maintain reliability. I will say, they have a heavier lever pull than both the Kaha’s and the Dominions, by a fair amount to the latter.
I pulled my Trickstuff pads from my Kaha’s to have a better idea of how they stop, with everything else being equal, tbh I feel like there is no difference in power other than I builds slower, more modulation, but required more lever throw to get there.
I was able to get the calipers centered on the rotors and have nearly equal piston extension front and rear. The bleed process brought back memories but I used a miniature hose clamp to secure the hose to the barb at the caliper which made it a lot easier to pull a vacuum and dislodge any bubbles in the caliper before I pulled the diaphragm and performed a push bleed from the caliper. The front brake was pretty poorly bled from the factory, the rear was perfect (based on lever feel prior to cutting the hoses) can’t wait to put some laps on them and hoping, pun intended, they solve my weird reliability issue that comes and goes with the Kaha’s…
Kaha dead stroke seems the easiest to get ultrashort. Mine is 6-7mm. The firmness is unrivaled. However, the lever shape is not great and no tooless on the trail reach/bite adjust. The bite point grub screen requires removal of the lever from the bar in my experience. Parts long term are also a concern.
The hopes seem like the best option going forward. Would have liked a bleeding edge port and larger resivour but finally some company has lever options! Been saying that’s needed for years. Parts are obviously not an issue.
I might give these a go when they come out with the power levers
My guess would be they've introduced a 17mm piston and have gone 18/17 for GR (+6%) and 17/16 for the TR (+6.5%).
What is surprising is that they have decided to use the same pad (V4?) in both because the smaller pad in the E4 was one of the main reasons it felt different to the V4. It's good they've added a different sized piston though as the E4 pad wear was really uneven.
So what hoses are the pros using?
Neko and Dak were using Saint hoses a couple years ago. I made that change on mine. Agree it feels more direct.
I’ve seen many using the shimano bh59 hose
If I’m not mistaken they mentioned it on a MoiMoiTV video as well at some stage
If you go through all the tech ransoms on the red site you’ll see some from ages ago
those are just bh90 hoses
bh59 is worse for sure

Locking the front wheel on asphalt with grippy front tire and long travel fork requires crazy stopping power.
I think you and Primoz are thinkin' too hard, and that's not meant with any holier than thou. The pads will leave a witness mark on the rotor's brake track, even on initial bed in. I'd be cautious introducing anything that may negatively affect pucker power, such as permanent marker.

The new Hopes are revealed, I assume 6% increase in piston size from 18/16 means 18/18mm

Added lever bleed port puts them on my list of brakes to try now.
Im curious to see how it is, it looks to me it’s in a position where air can get trapped underneath the diaphragm, so I’d still bleed them the normal way
Too bad they aren't compatible anymore with that massive 3.3mm rotor
GR4 and TR4 both use larger leading pistons (as per video).
Still DOT?
I think so, no details that I’ve seen about that, now they have the same pads GR and TR but both different from e4/v4 shape
They most likely realized almost nobody uses them, they’re too expensive and heavy
Thanks!

Vented rotors are no loss—PITA to true.
The raidic hose connectors are amazing. No barbs or expendable parts—totally resuable. I use them on my hopes btw

Both brakes have a 17mm piston present, that's a new size for hope.
