HIAORS Rear Brake Master Cylinder Reservoir for Yerf Dog GX150 150cc Yard Card Go Kart ATC 250R 1982 ATV 110cc 125cc Chinese Dirt Bike Pit Bike Golden

Center line of mounting holes did not match my old unit and had to elongate two mounting holes. Throughout the full cycle of operation, volume of brake fluid seems very little - perhaps my brakes need a higher volume of fluid. (bleed brake lines)

All good except this does not perfectly fit a Redcat 150 I had to do some fabricating to make the holes line up for the mounting bolts, but if you need this for a Redcat it still can be done.

I installed this on a Firefox 620 off road go kart. Bolt pattern was spot on. The adjustment bolt that links to the pedal assembly had to be cut down (about 1"). I also shortened the reservoir line a bit. Works great.

Simply had to trim the bolt to get the correct peddle position and it is working great. Love the gold look

Good value for the money with a little modification done worked like a champ on Colman kt196

Hard to be useful when there is a huge hole in the fluid reservoir.

Didn’t fit my 125 pitbike, but seems to be of ok quality

This was the product that I ordered, but it did not work right out of the box.
