JFOYH Upgraded E4 MTB 4 Pistons Hydraulic Disc Brake Set with Cooling Metal Pads for Mountain Bike(Pre-Bled, Front and Rear)

High quality for the price. They look amazing. They do not look cheap! Performance is pretty good. Many points between on and off. Levers are very comfortable.

Bought these to replace the 2 piston tektro on a zugo electric bike my girlfriend and I ride, prior it was not capable of locking the brakes with both of us on it, now it does easily. The lever feel on these are awesome and so are the color, feels a lot like my dhr evo brakes I have on my surron , and these are way nicer then the stock surron brakes I would definitely recommend these. I did have to swap out the rear line for a longer one and had to use new fittings and do a full bleed as it doesn’t come with any but I own a Ebike shop and had all the parts on hand (may need to take to a shop to have a longer line installed and bleed for some bikes)

I really like the look of these brakes. And the lever feel is on par with offerings from Shimano and SRAM. But within 2 rides my rear caliper already developed a leaky piston.The giveaway was squealing, ineffective braking. That’s a clear sign of brake oil contaminated brake pads and rotors. So I removed the caliper from the bike and sure enough, brake oil on the outside of the brake pad and oil bubbling from the edges of one of the rear pistons.The front caliper is still fine, but I don’t have much faith in its longevity.One other downside of these is bleed kit compatibility. Nowhere do they tell you which connections you need to bleed these brakes so you’re stuck guessing which fittings are required. Not a deal breaker, but annoying. The piston leaking is however a deal breaker.

Upgrade for heavier Fat Tire Bike. locks up when needed, Rolling the front with 180mm rotor with these green calipers because mine frame color is green as well.

Absolutely love the way these brakes feel and look but when they arrived I was disappointed to see that there was no brake pads or bolts to hold the pads into the calipers but I guess I was lucky I had ordered extra pads and had some bolts laying around

Good look. Good feel. Nice budget upgrade.

These are the best brakes I've had on a MTB however make sure you upgrade the pads, the pads that come with them are so bad it almost made me return the set but I thought I would buy better sintered brake pads and wow what a difference, the brakes are so sharp and responsive its insane, I barely have to touch them.Also keep in mind with any brake pads... you need to break them in so it took about 25miles for me to gain full power.Buy these with confidence.

May work for some bikes, but didn't fit my RockShox fork properly. Had to use longer bolts and metal washers to build up proper distance and slant for my 180mm rotor.

Looked good but cheap quality
