Now available from Scott Drake Mustang, the safety and increased stopping power you have been looking for on any 1964-70 Mustang in a very easy to install unit. This setup utilizes a new Bendix style power brake booster with increased sensitivity and a new large capacity dual chamber master cylinder, specially designed mounting bracket to allow direct bolt in while retaining original brake pedal assembly and clearance of the shock tower. The pushrod is preset but is adjustable to move the pedal height up or down. The only modification necessary is bending new lines from the master cylinder to the distribution block. We also offer a rebuilt distribution block part number C7ZZ-2B257-A which is not included in the Power Brake Conversion. This part is recommended for all 1964 - 1966 disc brake cars. This kit is easy to install and works excellent on both drum and disc brake cars. This is a very economical solution for an improved braking system along with the added safety of a dual-chamber master cylinder. Note: 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. Designed to fit models with automatic transmission and 4-wheel drum brakes.
