I'm just finishing up a '65 Chevy II SS, tube chassis 18 month long build. I'm using all new brake components, including Strange discs all the way around, all new lines, residual valves front and rear, proportioning valve, and line lock, and new Strange master cylinder ( it was bench bled). I must be missing something, as I've bled this entire systerm over and over, and always come up with the same scenario. The first pedal pump goes to the floor, then the pedal is all the way up, and loses no firmness no matter how long you hold it. I've bled manually, and with a power bleeder....the same results. Brakes have always been a problem with me...I hate them. Thanks for any input.
