1964-1966 Mustang Brake Booster with Wilwood Master Cylinder and Proportioning Valve

Mustang fans rejoice! Finally, an attractive Wilwood master cylinder paired with a Bendix style dual diaphram brake booster for our classic mustangs! We’ve teamed Wilwood’s newest compact master cylinder with a 7” Bendix-style dual diaphragm booster. The small, compact, space saving design fits nicely between the firewall and shock tower, and is an ideal choice when fitting your car with a hydraulic clutch kit (standard 9” boosters don’t offer the space required to install a hydraulic clutch master cylinder).

Prior to the release of Wilwood’s new compact master cylinder, such a product wasn’t achievable as the Wilwood Master cylinder was too long to clear the shock tower. This new design, mated to a 7” booster, can only be found through Autoworks Parts. Yes, this is a custom product that’s not even available through Wilwood!

  • Ships Pre-Assembled
  • Includes Wilwood Proportioning Valve assembled
  • Compact design fits in classic mustang engine bays
  • Sleek black finish
  • Available for both power or manual original brake pedals
  • Helps make clearance necessary for installation of hydraulic clutch kits
