The master is for power brakes but also can be used for manual brakes because it has the deep hole for the brake lever push rod. I did not use residual valves and have a great pedal and excellent stopping ability. The master is on my '48 Chevy 3800 that has '54 3800 front and rear brakes. Installation was done 6 years ago. 18,000+ miles with no problems. The NAPA part number is M1974. | | |
