GM installed a dual master cylinder in all 1967 and later Corvettes as a safety feature. Multiple reservoirs allows for continued braking if a rupture takes place in your front or rear brake system. Now you can get that same security for your older mid-year Corvette by installing a Zip conversion kit.

The 1963-1966 dual master cylinder kit converts your single reservoir to the 1967 style master cylinder. Complete bolt-on kit includes:

  • New 1967 style master cylinder (1" bore)
  • Proportioning valve with bracket
  • Brake lines to proportioning valve
  • Brake line to left front brake line block
  • Brake line to left rear block
  • Brake line frame blocks

Note: This bolt-on dual master cylinder kit requires no modification to original parts and does not require any custom lines or connections to be made. Conversion back to original is possible when desired.
