Description

Upgrade your factory power brake booster and master cylinder with LEED Brakes' 8-inch Dual Diaphragm Power Brake Booster and Master Cylinder Kit. Designed for vehicles with factory 4-wheel drum brakes, this kit features a 1" bore dual bowl master cylinder. The kit includes an 8" power brake booster, mounting brackets, an adjustable proportioning valve, and a 1" bore drum brake master cylinder. This comprehensive kit ensures easy installation and allows you to fine-tune rear brake pressure to prevent rear wheel lockup. LEED Brakes' power booster assemblies are shipped fully assembled, ensuring proper adjustment of the pushrod between the power booster and master cylinder and proper fitment of all valves, lines, and brackets for a trouble-free installation.
