Rear Brakes are not working at all
I am driving a 1956 Chevy PU, 75 Camaro front clip, 10 bolt posi rear from Nova. Disc front brakes, rear drum. Dual master cylinder with aftermarket vac booster. Front brakes work well, rears have little to no stopping power. I adjusted rear shoes and bled wheel cylinders, fluid comes out. Rear wheels will not even stop on jackstands. When I push the brake pedal the fluid comes out of the master cylinder ?? Possible bad MC or proportioning valve ? I'm at a loss at this point.
