Power brake conversion for the 1967, 1968, 1969, and 1970 automatic transmission Ford Mustang with disc 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.
May require bending new lines from the master cylinder to the distribution block. 
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.
