JFOYH 4-Piston MTB Hydraulic Brake Set with 160mm Floating Disc Rotors, Front and Rear Hydraulic Disc Brake Kit For MTB(Pre-bled, Included Original Pads)

The original cable disk brakes were not doing their job, so I replaced them with this set, and it made a huge difference. My bike is a heavy steel frame with 26x4 Fat Tires, so I needed something with some stopping power. The pictures in my review also show the upgraded 203mm rotors that I swapped out, but it was not needed because the 160mm was more than strong enough to look my wheels up.I did run into a few problems with the install, but my issues may be different from bike to bike. In my case, the disc rotor was too close to the caliper mounts. The screws on the floating rotor was sticking out a tad too far and was rubbing. So, I had to add some additional washers to push the calipers out. I did not have this issue on the rear brakes and it installed without any issues.Some of the great features with these brakes is that is pre bled so it was plug and play after I installed it. It also came with a brake pad spacer that helps you center the rotor during the installation. You still need to fine tune it, but I gave you a great starting point.The hose was motor than long enough for a standard size adult Fat Tire bike. I really like the rotating hose connector because it routes the hose very nicely, no matter how the brake is positioned.So far, the brakes have been solid with no leaks, but….. I am wondering if they have properly bled because sometimes, I need to pump the brakes before it works fully.

I can't speak for the discs/rotors, as I was just upgrading from cable to these hydrolic calipers. But I can say for certain that they absolutely grab, and will lock up your wheels. They look great in yellow, almost gold. Several months later and have zero leaks and zero loss of performance. Build quality feels nice. Installation was not difficult, but I wish the lines were just a few inches longer for both calipers. I can also say that these things will withstand a mild crash, unless it lands directly on the lever or something.

These are the nicest breaks I ever installed, and this is my 3 different kits. With that said I wish they had it in e bike brakes. That's why 4 stars.

Arrived on time, easy to install on a large 29 wheel Rock Hopper, cables were perfect length. Used existing 160mm disc and didn’t need the base adapter as it fit precisely to 75mm frame base. Did not cut and thread through frame, used existing frame tie downs and zips, barely noticeable.As far as braking performance totally blows away the factory mechanical that came on Specialized Rock Hopper. Those original breaks were never able to skid stop and these are, a good indicator of braking performance. As far as performance over time we shall see but right out of box everything was easy and perfect. Make sure you order correct left/right combo as cable lengths differ by design. Also make sure to measure brake base and disc diameter.If you are looking to upgrade from mechanical these are amazing. If you are already using hydraulic and looking for better I can’t say. But a great way to leave behind all of the adjustments of mechanical and benefits of hydraulic!!

Haven’t used them yet. Why does it not come with instructions. These are way different than what I have. You should send install instructions.Why are these brakes not releasing they are stuck like that. Why?

Recently picked up an old Specialized mountain bike and it had been upgraded to disc brakes, but they were terrible. Came across these while looking at a recommendation a YouTube made (the newer upgraded version of these) and didn't want to spend that much money. It's my first mtb and I'm not going to be hitting any hardcore trails.. Just beginner stuff.Install was very easy and with the correct tools shortening the rear brake hose was easy.Lever feel and modulation is great. Initial bite isn't too harsh if you apply pressure slowly but they'll definitely stop you quick. Definitely recommend these for anyone looking for good brakes without breaking the bank.

Rotors were slightly bent. Unable to detect this until you mount them. Good price and value but rotors should come unbent.

When I saw them, the price was 44$ but when I was going to buy them, the price increased to 74$ still cheaper than other brands, but I have to say, the breaking power is extremely high, they arrived in a nice box, inside an Amazon low quality bag, all good! I will buy them again and 100% recommend!
