FRAME MOUNT BRAKE BOOSTER KITS

 

Due to higher line pressures required with disc brakes, it is recommended that a power assist unit be added to the system. These vacuum assist units are the solution! Frame mount booster kits bolt directly to where the original master cylinder mounted (except 1955-57 Chevy car). Some kits include the pedal and others utilize the original pedal. Kits include: booster and frame mount brackets, linkage to connect to the pedal, and master cylinder. Disc/drum and disc/disc kits also include proportioning valve and bracket assembly. Kits available in 7" or 8" and both single and dual diaphragm. If not specified, default booster diameter for your application will be provided. Note: #CP6XX kits do not include proportioning valve assembly.

    4. Bolt the booster back onto the bracket.

    5. Using the hardware kit attach the pedal push rod to the brake pedal. Pedal height is adjustable using the heim joint. Once everything is complete make sure to tighten the jam nut. The aluminum spacer will be used in place of the factory clutch pedal if it is not there.

    7. With the booster and bracket installed, next you will need to bench bleed the master cylinder before installing.

    8. Put a 3/8’’ vacuum line from the booster to the manifold vacuum. Be sure to double check that all brake lines are hooked up and then begin to bleed the brake system.

    9. Lastly make sure that the pedal is on firmly and begin use.
