7-Inch Chrome Dual Diaphragm Power Brake Booster Kit with 1-1/8-Inch Bore Cast Iron Master Cylinder & Adjustable Proportioning Valve for 1970–1981 Chevy Camaro & Pontiac Firebird

Upgrade your 1970-1981 Chevrolet Camaro or Pontiac Firebird with this 7" chrome dual diaphragm power brake booster and master cylinder kit from LEED Brakes. Designed for classic GM F-Body vehicles, this combination includes a chrome-plated 7" power brake booster, 1-1/8" bore cast iron master cylinder with chrome lid, and adjustable proportioning valve.

The 7" dual diaphragm power brake booster is hand-polished before chrome plating for a high-quality finish and is designed to mount directly to your vehicle's factory firewall. The included cast iron master cylinder features a 1-1/8" bore and chrome lid, while the adjustable proportioning valve allows rear brake pressure to be fine-tuned for your specific braking system.

This Camaro and Firebird power brake booster combination offers a polished appearance and adjustable brake pressure control for compatible front disc/rear drum and four-wheel disc brake applications.

Important: This kit includes an adjustable proportioning valve rather than a fixed disc/drum or disc/disc valve. Verify compatibility with your vehicle's brake configuration and confirm the appropriate master cylinder bore size before ordering.
