GM Truck, C10 Pickup, K10 Pickup


Compact-10 Series 8" Dual Diaphragm chrome plated power brake booster & 1-1/8 in Bore Master Cylinder. This 8 inch power brake booster is hand polished before a chrome finish is applied for a top quality finish. The mounting bracket is a direct fit to your factory firewall. The 1-1/8 in Bore chrome aluminum master cylinder is designed to work with your stock disc/drum brakes and most 4 wheel disc brake upgrades. The Compact-10 series boosters are designed to give you more engine & wheel well clearance over the stock power brake booster. This type of power brake booster gives you the look & brake performance you want out of your truck.

Will work with factory cast iron master cylinder & most aftermarket Master Cylinders. Will not work with stock aluminum master with plastic reservoir.

If you would like to purchase a kit without a master cylinder check out item number PBKT6011. Standard Finish kits also available.

Adding 4 wheel disc brakes, use proportioning valve PV4_B as a direct replacement for your stock disc/drum proportioning valve.
