MEROCAM4 4-Piston Mountain Bike Hydraulic Disc Brakes Hydraulic Bike Brakes Front 800mm and Rear 1400mm with PM Adapter for 160mm Rotor

Good hydro breaks 4 star haven’t had them that long works great with the sram centre line 203 rotors loads of stopping power

Very good

I bought these brakes for my razor sx500, I also got some new disks for it, they work great, perfect stopping power and they fit good, without making any modifications to the frame.

good brakes , gotta brake em in but works fine

Great Brakes! Just as good as the top brand name they replaced on my bike, probably exactly the same.

Went to install these brakes and found the brake handles had been installed incorrectly. Left on right and right on left calipers. I had to take to a bike shop to have the lines switched and brakes bread. This service cost more than the kit had. Value isn't there when having to have them serviced to operate. Was going to contact the seller before leaving this review but the only option was to return or replace. No contact option.On the bright side, the brakes grab so well I had to be really careful to not grab the front so hard I'd crash while the brakes were reversed!

Not sure on performance yet, the feel is solid, the finish leaves a bit to be desired. The main problem is that the front and rear brakes are pre set up opposite of standard us setup (standard meaning rear brake on the right front on the left... it’s opposite of that). So I need to switch the hydraulic lines and bleed the brakes. I’ll update in either direction if I’m totally impressed or disappointed. Otherwise, they appear to be an upgrade from my worn out dual piston xt brakes from the mid 2000s.
