BUCKLOS MTB Hydraulic Disc Brakes, Mountain Bike Left Front 800mm Right Rear 1450mm Hydraulic Brake Set Aluminum Alloy Levers with Calipers PM/is Adapter Fit EBike/Fat Bike

I have a 13 year old MTB and the original Promax mechanical brakes really were awful. I decided to upgrade to hydraulic brakes. Since I ride mostly through the neighborhood, I didn't need top of the line brakes. I was very suprised with how well these brakes worked right out of the box. They bolted right up with no modifications (160mm Promax rotor). I didn't have to bleed anything either. They have very good stopping power. Time will tell if they hold up or not. But for the price, if I get a few years out of them then thats fine with me.

For one brake it could be cheaper but for the price it serves its purpose easy install if you know what your doing , quality is great pads stop on rock literally lol

I can't do a flush and vleed for the price of just replacing a set of brakes with these. Wish they made something similar with two and three wire cut-offs for e-bikes. They would be ideal for working on any bargain e-bike.

The price for these brakes were great so I went ahead and bought 2 pairs to update the brakes on some older spare mountain bikes. The swap of levers took less than 5 minutes and I didn’t spill 1 drop of brake fluid. All you need is an 8mm wrench. And something to lean the lever against so the open end is facing up. I was prepared to bleed the brakes if needed but no fluid was lost. Here’s what I did.1. Pull the rubber covers off.2. Use the 8mm wrench to unscrew the nut. You just need the wrench to loosen the nut, you can unthread the rest by hand. Do not pull the hose off yet.3. Repeat step 2 on the other handle.4. Pull the hose off, keep the hose end and handle thread end facing up.5. Pull the hose off the second handle and replace it with the one that was removed before.6. Connect the other hose and handle.7. Put the rubber covers back on and your done!I gave these brakes 4 stars because they don’t stop as well as I expected. They do the job, just not as well as I hoped. I do have used brake discs so that might play a factor. Still glad I bought these.

This fits right on to my razor MX650 frame. The only problem is the rear brake rotor is too small. I got a bigger 160mm rotor problem solved.

Update: after using these awhile the pads started to wear out, and when I went to turn the adjustment screws I discovered they were already all the way and you cannot turn the adjustment screw at all, only out. This means they charged the oil system with the bare minimum of oil in them, just enough to work. When it does come time for adjustment there is none. I suspect there's a way to add oil, but I shouldn't have to do that on brand new brakes. So they are as is, and you cannot adjust for wear. Also it comes missing important hardware where the surfaces meet and are supposed to be semi adjustable.. pads literally burn off and you can smell them burning, and as soon as there is the least amount of wear you have to add oil to the system, not an easy thing to do. To explain more clearly, the single piston will only come out a tiny distance because of the lack of oil pressure. These are unsafe and dangerous. They also leave out the adjusters that are supposed to be used on ALL disc brakes. They just bolt on and if isn't aligned perfectly aligned then oh well, because theres no adjusters. You can use your old ones but shouldn't have to and in my case I don't have any.

worked good fit right on out of the box litterly new brakes on in 15 min

Great product...!+++++
