DSE Brake Booster & Master Cylinder Kit (050107DS) - 1964-1967 GM A-Body
Bring a more modern, performance-oriented brake pedal feel to your classic GM A-Body with the Detroit Speed Brake Booster & Master Cylinder Kit. Part number 050107DS is engineered for 1964-1967 GM A-Body applications and combines the major power brake components into a direct bolt-on package. Detroit Speed pairs a compact 9 inch dual-diaphragm brake booster with a 1 inch bore aluminum master cylinder and reservoir, giving builders a matched solution designed to work with stock or aftermarket brake systems.
The 050107DS kit goes beyond the booster and master cylinder by supplying the application-specific components needed to complete the installation. Detroit Speed includes the booster bracket set, brake booster pushrod, two master cylinder fittings, firewall seal and seal plate, pedal clevis components, installation hardware, and instructions. The booster requires a minimum of 10-12 inches of mercury engine vacuum, making available vacuum an important consideration when pairing this system with an engine using an aggressive camshaft.
