[More Info]
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 1-year warranty, a new large capacity dual chamber master cylinder, specially designed mounting bracket to allow direct bolt-in while retaining the original brake pedal assembly and clearance of the shock tower. (However this Kit does require notching Factory Shock Tower Brace, therefore Export Brace recommended) 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 may be required depending on what the car is currently equipped with. This part is recommended for all 1964 - 1966 disc brake cars. 1967 - 1970 cars already have one from the factory but it is a good idea to replace it. This kit is easy to install and works excellent on both drum and disc brake cars. This is a very economical solution for your customers that are looking for an improved braking system along with the added safety of a dual-chamber master cylinder. Note: Booster requires a minimum of 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.
