When you put modern disc brakes on your 1955-1964 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
