Q & A

What's in the Box

When you put modern disc brakes on the front of your 1958-1964 Chevy full-size car (Bel-Air, Biscayne, Impala), you should update the master cylinder as well. Stock 4-wheel drum master cylinders do not have the capacity to supply the proper amount of pressure for front disc brakes. For best results, we recommend using this simple, bolt-on master cylinder booster kit on all front disc brake conversions.

  • 8" dual diaphragm booster
  • 1" bore master cylinder
  • GM style proportioning/metering combination valve
  • Master cylinder has outlets on both sides for ease of plumbing
  • Includes plugs for unused outlets on opposite side of master cylinder

Learn more about selecting the proper master cylinder for your vehicle by reading our tech article. Brake System Selection.

Specs

  • Outlet Fittings:  1/2"-20 and 9/16"-18
  • Proportioning valve comes with 1/8” NPT to 3/8"-24 IFF adapter fittings

1955-1964 Chevy Power Brake Booster Bracket, Passenger Cars
                        

This bracket makes it easy to convert to power brakes while keeping the master cylinder level. The bracket is designed to work with 1955-64 Chevrolet A Body and B body passenger cars such as the Bel Air, Biscayne, Impala and Caprice. The booster side of this bracket has the common 3-3/8” center to center both vertical and horizontal.  

  • Makes it easy to convert to power brakes
  • 3-3/8” center to center both vertical and horizontal - booster side
  • Designed to work with 1955-64 Chevrolet A Body and B body cars (Bel Air, Biscayne, Impala, Caprice)

Note: Depending on the application, this kit, in many cases changes the mechanical advantage or pedal ratio. With power assist less pedal pressure is required and to help eliminate some of the pedal travel the attachment location on the pedal arm may be further from the pivot point. You will need to have a straight alignment of the rod to the assembly and also a straight in alignment of the push rod to the booster.
