Ok so after finishing new suspension (B-52 kit pics soon to come). Drove it around and no back brakes. I did the disc swap awile back and it hasnt gone anywhere since. Bleed the hell out of them and the master cylinder is only pushing to the front brakes. Did some trash get in the MC during the swap and F up the MC. The rear of the MC (front brakes) is visually pumping. When the pedal is pushed fluid basicly squirts but nothing from the front. Cant even bleed the front(rear brakes) of the MC because it wont pressurize. So do I just get another MC?
