When you put modern disc brakes on your 1958-1964 Chevy full-size car (Bel-Air, Biscayne, Impala, 150 Series, 210 Series), 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 disc brakes. For best results, we recommend using this simple, bolt-on master cylinder booster kit on all 4-wheel disc brake conversions or as a power brake upgrade for 4-wheel drum brake applications.

  • 8" dual diaphragm booster
  • 1" bore master cylinder
  • Adjustable¬†proportioning valve for rear brake line
  • Master cylinder has outlets on both sides for ease of plumbing
  • 1/2"-20 and 9/16"-18 outlets

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

Notes

  1. Will not fit cars equipped with the original generator-mounted power steering pump.
  2. Front drum-to-disc brake conversions also require a proportioning valve to be installed in the rear brake line circuit. The proportioning valve modulates pressure to the rear brakes which is necessary to prevent the rear brakes from locking up in an emergency stop situation. This kit incudes an adjustable proportioning valve to allow for a proper installation of front disc brakes.
Some parts are not legal for use in California or other states with similar laws/regulations
