Shimano Deore XT M8000 2-piston Disc Brakes
The Good
The online discounted price.
The components (lever, caliper, hose) are all compatible with every Shimano brake of the last 20 years.
They're piss to bleed and if you're stuck in the middle of nowhere you can use literally ANY oil, eg Olive oil works fine (tested in the Alps!)
They work fine - power is average
Pads are available everywhere
The Bad
They're probably more reliable than anything, but they're still not exempt from the "master cylinder lottery" (ie they will eventually start to go wrong)
The levers are flexier than the previous version (M785)
They're only safe to use for 12 months before you should get rid and get some (identical) new ones
The finned pads are a waste of time and offer no noticeable "real" benefit
Overall Review
It's impossible to review these brakes without first mentioning that they're heavily discounted all over the internet, so the "real" price is closer to £100/pair (not including rotors). That makes them by far the best value performance brake available, from any brand before you even mention that they actually work pretty well too. They're light weight and pretty powerful, especially with a big ol' rotor. In theory mineral oil has a lower boiling temperature than DOT fluid, but I've never

The Good
Gobs of stopping power. Consistent braking. Tough as nails. Excellent lever shape and feel. Parts are easy to come by. Ease of maintenance, Shimano's are by far my favourite brake to bleed.
The Bad
Some times the lever requires a couple pumps to get things feeling right and the brakes grabbing. I was told this is an issue with the lever but I couldn't be bothered to send the brakes back and not ride and now I am just used to it. I did have an issue with a rear caliper leaking after 2 years of abuse and crashes, but I grabbed a new caliper on Jenson USA and tossed it on, gave it a quick bleed, and good to go.
Overall Review
These have been my go to brakes for years. I am a big fan of the way they grab. I couldn't care less about modulation, when I pull my levers I want the brakes to grab. I have used these brakes for everything from a 6 hour endurance event to trail riding to enduro racing and have no complaints. I had a couple issues with them, like the leaking caliper, but the new caliper is working perfectly with no issues. I would recommend these to just about anybody. They look great and can be found for a

SRAM Guide RE Disc Brake
The Good
Old Code caliper mated to new Guide levers - I use the Guide RSC levers instead of the stock R's and it's killer
The Bad
The RSC levers make a big difference
Overall Review
I've never had an issue with my RSC lever/RE caliper setup. It's basically a refined older model Code and kicks ass on a trail bike setup. I never bothered to try and use the stock R levers but with the RSC setup it's a solid 10/10. Way better power and modulation than the Guide caliper. Would recommend.

The Good
Unrivalled breaking power, Shimano reliability, easy bleeding, well built, good cooling, great one finger levers
The Bad
Poor modulation, wondering bite point
Overall Review
This break has saved my life so many times. However, due to the wondering bite point it has also put me in some scary situations. Absolutely some the reliability, easy bleeding, power and cooling this break offers. Hands down destroyed the competition until the new Code came along in 2017. Come on shimano, nearly perfect.

Total garbage
The Good
When they are below 80 degrees they work ok
The Bad
When the levers are above 85 degrees once you pull on the brakes they are on till you cool them down.
Overall Review
These would be good brakes if sram could figure out how to get a working set out the door. I have warranted 2 pairs and everyone i know who has a set has exchanged theirs. Avoid at all costs. Get some zees, they are life changing
