When you put modern front disc brakes on your 55-57 Chevy car, you should update the master cylinder as well. The stock 55-57 drum brake master cylinder does not have the capacity to supply the proper amount of pressure for front disc brakes. This simple bolt-on power brake assembly will ensure your brakes are operating at peak performance.
- Kit contains a 1" bore master cylinder with 1/2"-20 and 9/16"-18 outlets, 8" dual diaphragm booster, and a disc/drum combination valve (provides proportioning and metering).
- Also includes line to connect the prop/metering block to the master cylinder and the necessary hardware to mount the booster to your original 55-57 Chevy brake pedal.
- Measures 14-1/4" from firewall bracket to end of master cylinder.

Includes proportioning/metering valve
If utilizing the original equipment generator mounted with the factory brackets on the driver’s side of the engine, interference to this booster/ master cyilinder combo may be an issue. Please check for clearance and usability at initial stages of install to insure proper function for both units upon installation.
