Info

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

Learn more about selecting the proper master cylinder for your vehicle by reading our tech article. Brake System Selection.

 

Installation Instructions

Notes

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.
