🔧 GOOFIT Rear Foot Disc Brake Master Cylinder Assembly with Oiler for 110cc-250cc ATV Quad Dune Buggy: Enhanced Braking Performance & Efficiency Review

In the Q&A section someone says it's good for a 5/16 disc. It's actually not big enough for a quarter inch. I had to cut it and make a spacer to fit my .250" rim. In any case, get ready for some machine work.

You get what you pay for. The product itself is beautiful and works very well. However, two main problems: the brake line is very short and there is no bracket. I had to order a longer brake line (the one on it is only about 24 inches long) and without a bracket I had to make my own. If nothing else, they should include a mount.

So far it seems to be made of quality materials and the design is pretty good. I installed this on a homemade go kart but unfortunately it didn't work. After some research I discovered that one of the banjo bolts on the brake line was missing a hole for fluid to enter. Most likely it was a simple manufacturing defect, and finding a new Autobahn wasn't difficult. I've since ordered a new cheap line and have to recheck the caliper and master cylinder when I put a new part in.
