7in Dual Zinc Booster AF X 1-1/8in Bore Master

The 7in Dual Zinc Booster AF X 1-1/8in Bore Master is a critical upgrade for heavy-duty vehicle platforms requiring enhanced stopping power and reliable hydraulic pressure. Designed by LEED BRAKES, this kit serves as a robust solution for operators maintaining GM-based fleet vehicles or specialized tactical transport units that demand consistent braking performance under load. By integrating a dual-diaphragm booster with a large-bore master cylinder, this assembly ensures that even larger vehicles can achieve shorter stopping distances and improved pedal response.

This unit features a 7-inch outer diameter dual-diaphragm booster, which provides significantly more vacuum assist than single-diaphragm models in a compact footprint. The 1-1/8 inch bore master cylinder is constructed from high-strength steel and features a dual integral reservoir to maintain separate hydraulic circuits for front and rear axles, enhancing safety in the event of a line failure. The entire assembly is finished in a gold zinc plating to resist corrosion and environmental degradation, ensuring longevity in harsh field conditions.

For technicians and fleet managers looking to buy a reliable brake upgrade, this kit is engineered for various GM applications and offers a straightforward installation process for compatible frames. The combination of a dual-diaphragm design and a 1.125-inch bore makes it ideal for vehicles with disc/disc or disc/drum configurations where high fluid volume is necessary. Reviewing the specifications confirms this LEED BRAKES master and booster kit provides the mechanical advantage required for mission-critical mobility and vehicle control.
