JFOYHzoom HB876 4-Piston Pre-Bled Hydraulic Disc Brake Set for Mountain Bike, Bike Disc Brake Kit with 160mm Rotors, Front and Rear Levers(PM Adapter Included) - Left-Front&Right-Rear

Installed these on a full suspension MTB. Hit 40 mph top speed on the decent and had zero issues with the brakes. They worked perfectly, and stopping power was excellent. They made my ride so much more enjoyable, as the old brakes were cable operated disc. Five stars..

Honesty from the start...I bought these because for the price they included rotors. If I didn't have to replace a bent rotor, I may have chosen differently. That said, I am absolutely satisfied with my purchase. I purchased these brakes for an SE Bikes Fast Ripper which has a 10 speed shifter to contend with. I like my brakes to be one finger brakes...meaning only index finger. This requires the lever to be clamped 1" or more from the grip when the lever is multi finger (like these). They have exceeded my expectations in regards to performance and with the addition of an Avid adapter (https://www.amazon.com/gp/aw/d/B001U6KI78?psc=1&ref=ppx_pop_mob_b_asin_title), I have my brake lever and shifter installed where I wanted. I have installed new housing to utilize the internal cable routing of my frame and had zero issues bleeding these brakes. I would highly recommend them to anyone.

Before this install I was a complete amateur and didn’t know a thing about bike hydrologic brakes and here are the things I learned about this brake kit.• before buying, make sure you have a bleed kit because you’re going to need it.• the rear hydraulic line is short which may require you to buy a separate new line (like I did) to install it.• if you do require a new line then you will need a needle driver tool (sold separate).both lines were too short for my bike so I replaced and bled both. In conclusion this brake kit performs great after some custom work. But I don’t recommend it unless you want you have some knowledge on how to install hydrologic brakes.

So far so good on these. I decided to upgrade the Avid BB5 mechanical disc brakes that came on my Specialized Rockhopper (2009ish). I've been taking a lot of steep, technical trails with big roots, rocks, burms and drops lately. Downright scary with the close to zero stopping power of the BB5, even after brand new pads.These brakes are a huge upgrade on the ride. So much more confident that I've got the braking power when needed. Installation was straightforward. The only issues were one of the rotor bolts was cracked (poor manufacturing) and for my old 18" 26er, the rear cable is a few inches long. I'll probably shorten that in the future.So far 8 or so rides - no fade, no leaks and great performance. Well worth it.

Easy to install and get the bike back on the road again.

If I was able to not get these and get 4 piston shimanos I really should have gotten the shimanos

I Have had this Motoped for many years , being that its is a motorcycle with bicycle brakesIt is the perfect place to test brakes, I have purchased different sets of calipers/ brakesAnd was still not satisfied until these .Now i can stop ! , now i can lift the rear tire under brakingI also like the lever length, the Hayes brakes i had I could only get 2 fingers on the leverOn these i can get 3 fingers ,I recommend these brakes

Great product I have an old iron horse bike, I used the frame and installed all new updated components on it and used this kit on it I been using it on steep downhill and they work great same as my real expensive bike, will use them again any time
