here's the story. all new disc/disc set up from cpp . booster/mc/proportioning valve . all came as a kit. low spongy pedal. over a qrt of fluid bleed through it. rear ebrake adjusted tight . already replaced the mc but still crappy brakes. dont see how any air could still be present. any ideas ?

this will be the last CPP part to ever hit my shop. the new aluminu mc was full of shavings.
