Power brake conversion for the 1967, 1968, 1969, and 1970 automatic transmission Ford Mustang with drum brakes.
Uses a new Bendix style power brake booster with increased sensitivity.
Made with a large capacity dual chamber master cylinder, mounting bracket to allow direct bolt in while retaining original brake pedal assembly, and preset adjustable pushrod.
Booster requires a minimum 15 pounds of engine vacuum pressure at idle for maximum stopping power.
Some high performance/high lift camshafts may not create enough vacuum.
Stock engine vacuum pressure is 18 pounds.
