HIAORS Rear Brake Master Cylinder with Reservoir for Yerf GX150 150cc 3206 4206 3209 Go Kart Honda ATC-250R Chinese 70cc 90cc 110cc 125cc Dirt Bike Black

Had to cut and shorten the plunger to make it work on my go-cart other than that it works great

Leaked bad. Oring lip had a rough casting. Top had to be sanded .010 down to increase pressure on oring. Back fed line from caliper to master cylinder with syringe. Works fine now after 2 hours of work. Also, get copper sealing washers.

Ive gotten two of these they are perfect, easy to install, stop fast. Love it!

Fash shipping item as described

piece of crap. didnt work.recieved a replacement and also didnt work.

Acquired a stripped atv frame for a monster truck go cart project. Fit right where I wanted it and works well. It was very difficult to bleed though. Only way I could get the air out was to gravity bleed it.

Installed on a go kart, bled 10oz brake fluid they, no bubbles only fluid drained out bleeder, zero stopping power, very disappointed

Did not work for my build. Stroke is very short. Hard to bleed. Doesn’t move enough volume

Garbage leaks
