January 20th, 2009


Proper operation of your brakes is essential for your safety and the safety of others. Any brake service should be performed ONLY by persons experienced in the installation and proper operation of brake systems. It is the responsibility of the person installing any brake component or kit to determine the suitability of the component or kit for the particular application. After installation and before operating your vehicle, be sure to test the function of the brakes under controlled conditions. DO NOT DRIVE WITH UNTESTED BRAKES!


Take time to read all the literature that came with this kit. Check the provided list of parts against what you received to ensure all parts are present. While this kit was designed to make the process of changing brake parts as simple as possible.  NOTE: WITH SOME KITS IT MAY BE NECESSARY TO MAKE MINOR CHANGES TO YOUR CAR!


Before operating the vehicle after installation, test the function of the brakes under controlled conditions. Make several stops in a safe area from low speed and gradually work up to normal speeds. DO NOT DRIVE WITH UNTESTED BRAKES! Always utilize safely restraints when operating the vehicle.
Will not fit 292/312 engines with the original exhaust manifolds or big block cars from 1957-59.

Booster Kit includes the following components:

  1. Power booster with firewall bracket and pedal linkage.
  2. Dual outlet master cylinder
  3. Bench bleeding kit. (Included with master cylinder)


  1. Disconnect the master cylinder push rod from the pedal inside the vehicle.
  2. Remove the brake lines from the old master cylinder.
  3. Remove the old master cylinder.
  4. Mount the new booster to the four studs on the firewall with the bracket oriented as above.
  5. Connect the booster push rod to the pedal using the existing hardware. Adjust the push rod to have approximately 1/4” free-play at the   top of the pedal.
  6. Bench bleed the new master cylinder.
  7. Install the new master onto the booster.
  8. Connect the vacuum hose from the booster check valve to either the back of the carburetor or to   the intake manifold with the supplied manifold fitting.
  9. Connect the hydraulic lines as required. The line to the rear should go to the master cylinder outlet   closest to the booster.
  10. If you have disc brakes in the front you should use a dis/drum combination valve to balance the   system (Figure 1).
  11. The lines for drum brakes may be run directly with one line to the front and one line to the rear. As above the line closest to the booster should feed the rear drum brakes.
  12. Also drum brakes will require the use of a 10 lb residual valve to the front and a 10 lb residual valve to the rear (Figure 2).
  13. Bleed the entire braking system before operating. Check the pedal for firmness. If pedal is not firm bleed system again.
