Have '66 Coronet. Had manual drums Converted to power and front discs All new parts from Pirate jack including proper master cylinder, proportioning valve/metering valve. booster. Checked plumbing, all plumbed correctly. Brakes have been fully bled (multiple times, now at brake shop and he bled again) Car stop perfectly But pedal goes almost to floor before engaging brakes. Car stops when pedal is about 1/2 and inch off the floor. There seems to be no brake engagement for the first 2-3 inches of brake pedal travel UGH! Anyone know the fix?
