WEEROCK Hydraulic Brake Set Bike Disc Brakes Kit with Left Front 800mm Right Rear 1550 mm 160mm Rotors Aluminum Alloy Hydraulic Brake Fit for Mountain Bike, MTB

They were great the brakes themselves fit on the razor sx500 but you will have to buy a new disc brake which are pretty cheap and the brakes were surprisingly very easy to install and they feel awesome they are pretty adjustable I’d say but you will have to buy a new disc brake but I do recommend for the price they feel extremely smooth

READ THIS. DO NOT PULL THE BRAKE WHEN YOU GET IT OR IT'LL PUSH THE BRAKE PADS TOGETHER AND YOU WILL NEED SOMETHING VERY THIN TO MAKE IT WIDER SO YOU CAN PUT IT ON THE ROTOR. OMG AMAZING, these brake have some type of material that looks really strong and i don't even have to pull them down that far its like pushing a key on a laptop kinda range, this is my first hydraulic brake so its feels way better than my old line brakes on my ebike, this made a huge upgrade i would recommend. The length is very good, i can fit the cords easily where i want them, again the functionality is amazing, they work super good, installation i sOOOO easy too.

Came scratched up and I could have I looked past that, had oil on it and I could have looked past that but... The screws that came with it were poorly threaded and the second time I tried to stop they ripped the threads out of my fork and the calipers came off, and yes I tightened them to spec. My bike is fast and I take brakes very seriously. Now I'm left wondering how I'm going to install any brakes at all on my 1 month old bike. This quality issue has created a serious transportation issue for me and I'm at a loss.

Working very well. The disks cannot be installed on my bike as the original are bigger in diameter.

I don't know much about hydraulic brake systems for bicycles specifically, but from my general knowledge of tools n working on this n that I would say these are very decent quality being that they cost significantly less than any other option I found out there, n I did at least my due diligence. Came with handle, 31" hose n caliper pre-bled with pads n additional adapter bracket installed, rotor(zero scratches or scuffs) and all the screws needed for installation. The whole package for less than the vast majority charge for just the handle and caliper. The ONLY issue(only reason for only 4 stars) I see is despite bubble wrap on the handle, the caliper wrapped in separate plastic bag, all inside another plastic bag there were several cosmetic scuffs n scratches on the handle and caliper, but for the price I will gladly touch those up myself with some black paint or possibly even black marker. I haven't installed them yet but so far; All n all 👍 I would definitely recommend.

Started leaking from the caliper seal and leaking brake fluid on my brake pads would not recommend get name brand your with good reviews pls But if your just looking for something that will make it work bc they work

It's good for my bike

Definitely recommend this product easy to install and I didn't even have to bleed the front caliper that wasn't connected to the hose

Easy to install work perfectly!
