Better than cable discs I guess.

Weak brakes no power.

These came on my bike, they're a few years old. I'm running them with 203mm rotors. There is no bite and the levers will happily go back to the bars. I've changed pads, cleaned the rotors, bled them and they are set up and centred correctly. They are by far the worst hydraulic brakes I've ever owned.

The good:
Well they're hydraulic at least. Lever had a good feel to it with solid feedback. I had them on my bike for about a year and never bled them. Pad life was exceptional as well.

The bad:
High speeds caused the entire bike to vibrate and produced a terrible "warble" noise.
I spent hours attempting to adjust the brakes. They would just go back to "warbling." This was mostly because of the terrible caliper design. The pistons never fully reset like they should.
Stopping power was average. I never had a problem with it, but that's because I was riding mostly aggressive XC. Downhill guys should look elsewhere.
The calipers screached when braking. Horrendous noise that would scatter any wildlife within a quarter mile.

I did not attempt to throw any money into trouble shooting these guys. I sold the set and upgraded all together.
They'll stop your bike, but they aren't the best at doing it. It appears the guys that "really" enjoy the brakes are the ones that have them on their stock rig. No one buys Juicy's and has anything good to say about them.

Bottom line, look elsewhere.

None

Not reliable, loud, make a lot of vibration

I got these brakes on my Santa Cruz blur lt back when I bought the bike. From the start I had problems with them. They were always rubbing and we're getting really warm fast. Now the rubbing problem is better but they still get warm fast and now they are loud as can be. And the stoping power just gets worst and worst every ride. Just weak and poor all around. I have been told that I should upgrade to Shimano XT or SLX brakes and I'm going to and hopefully it will be soon.

Great stopping power, easy to maintain, and great price.

None so far...

It's funny how many poor reviews are given by people that obviously have no clue how to fix their own brakes. These are super easy maintain, and work excellent wet or dry. (Easily will flip you over the handlebars if you slam on them!) These bad boys came pre-installed on my 2011 Trek Xcalibur, and they are still going strong! I've had to bleed them once, due to a snagged line that caught on an obstacle, and tore it off, but with the avid brake bleeding kit, this was a simple job for one person to do. Took me approx. 15 mins, and I've never done it before. Technical people will find it easy to follow the directions and have this done in no time. Other than that, amazing stopping power even after 600+ miles on the bike through all types of mud and streams, etc... I would definitely recommend these to anyone wanting to get into disk brakes at a good price level. Yes there are better systems out there, but not even close to this price range.

I have not used other systems, as they are very expensive, and these still work great, so I have no reason to upgrade yet....

I've used these on my bike for almost 2 years. The only problem I've had is that they occasionally chatter/growl. A new set of pads ($15) solves it.

They worked ok for a year and a half.

These brakes came stock on my Trek Fuel. They worked fine for a while, but recently I have been having problems constantly with them: I have to frequently realign the brake pads on the front rotor - they rub and squeal a lot. And my rear brake just took a crap. It's been bled multiple times, I replaced the small parts of the lever and it can still be pulled all the way to the bars. No idea what's wrong with it and they are getting replaced ASAP. They worked ok for me for about a year and a half, but they just aren't reliable and are turning into a headache. I give up on these.

There are better brakes out there, I just know it.

Good when they are working correctly

SQUEAK! they make my bike unrideable. no lever reach adjustment

I struggled with these for years. squeak. They came with my new GiantXTC in 2010. squeak. They caused so much vibration, that Giant replaced the bike frame with a new 2012 XTC frame. They squeaked less on cross country trails. But when I went to the moutains they Howled, and sqeaked mercelessly all the way down the mountain, especially when using lightwieght rotors. I was told for years to get Shimano XT disc brakes to solve the problem. I finally did. I wish I had done it years ago. I do not understand why Juicy3s make so much noise and vibration, and Shimano XTs do not.

Avid BB7 - love those
Shimano XT hydraulic disc brakes - AWESOME

Nice pop, look sharp, reliable

I love these brakes, personally. That's because I have had good luck with mine. They trump the balls off the Craplixir 5's I just replaced.

A lot of grip for your money. Work well when wet. Low maintenance. Smooth. Very easy to install new pads.
Have had these brakes for three years, and not had to service or bleed them once, and still as strong as the day I got them.

Not encountered any problems as of yet.

These brakes are excellent. I honestly don't see how they get a bad rap.
If you want a hydraulic disc break for a very reasonable price, get a pair of these. You won't be disappointed.

None.

Constant rubbing.
Have to be bled frequently as in every 2 weeks.
Just plain shi*house.

Absolute crap, do not buy. I've had these braked bled 4 times in the past year and a half. They go strong for about 2 weeks then back to pulling all the way to the grip. I have changed the hoses and pads many times and still no difference. Please im begging you do not buy these brakes, get some shimano xt's on special or something similar.
