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

Muy bueno producto por momento no me ha dad problema.

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

Worked great! I had to cut off some of the bolt plunger for my go-kart. But it seemed to do the trick.

Bought this one to replace an existing master cylinder that got wrecked. Could not get to function completely, even after bleeding the system with a vacuum bleeder. The master cylinder will push fluid fine, and I can watch the piston/brake pad move like it should. But when the brake pedal is released, the piston retracts too far, leaving too much of a gap between the brake pad and disk. When the brake pedal is pressed again, the piston/brake pad will move to close the gap, but it is almost at the end of the master cylinder travel and it will not squeeze very hard. I dont know what is causing it- but the only new thing in the brake system is the master cylinder.

Fash shipping item as described

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.

Leaking fluid

Easy to install, great replacement on a Coleman go cart

This product didnt work I just installed it and it doesnt create pressure
