Hydraulic Rear Disc Brake Caliper System Pads Disk Rotor For 150cc 200cc 250cc Dirt Bike Quad ATV Gokart Go Kart Dune Buggy (BLACK)

Good quality for the money. One caliper locks up the rear axle on my go kart. On dirt or pavement. Got a little creative and set it up as a hand brake. $50 for the kit and a couple hours of fabbing up brackets to mount everything. Worth ever penny and second of my time. So much fun!

I have a 250 ATV, X-Pro or Tao Tao, its labeled as both, but this will not work on it.Otherwise it seems to be made well, no problems. If you have a 150 I'm sure it'll work great.

The brake system works well for the gokart I’m making for my sons. I would recommend this system for anyone making a gokart.

Overall, I'm happy with the brake. Strong stopping power. I did manage to let air into the line, and was worried of not being able to bleed the brake. I was able to successfully bleed the line by straightening out the flexible line so that air bubble could flow back up to the master cylinder and reservoir. Also, I put the calipers at the very bottom, and with the caliper bleeder valve pointed up (loosened the bleed screw, gave a couple brake pumps, to let any air in the calipers up and out). Success.

Works great, had to fabricate a way to mount rotor to axle but real nice. Hard part was the fabrication but not terrible

Why does nothing include instructions anymore? I didn't buy this as a direct replacement. i'm doing a conversion on a golf cart. I have no experience with disk brakes so some instructions would have been nice. I didn't know whether they worked on a push or pull, i assumed pull given the type of linkage it had, well i was wrong and ripped that out. got the washers flattened back out and everything back together and i still had no brakes. never bled brakes before, wasn't really sure how but after some you tube videos i figured it out with the caliper off, however in the process the pads fell out, again another time instructions would have been helpful on how they go back in. finally got everything cleaned up and put back together and brakes work. would have been a much simpler job if they came with instructions.

I used this as a driveline brake on my kid's rock crawler. I was worried it wouldn't have the stopping force, but it works very well.

This master cylinder does not hold pressure if you try to bleed the line. So if you buy it go ahead and replace everything. Even if you only need the cylinder it’s probably not gonna work out and you’ll waste about an hour trying to build that pressure back up for it not to work.
