8in Dual Power Brake Booster 1in Bore Master

The LEED BRAKES 8in Dual Power Brake Booster 1in Bore Master Cylinder combines a high-displacement dual diaphragm booster with an integrated dual reservoir master cylinder in a single compact assembly. This configuration delivers consistent brake pressure modulation across Mopar B-Body (1962–72), D-Body, and F-Body (1970–74) platforms without requiring external component integration. The 8-inch outer diameter housing and gold zinc-plated steel construction provide corrosion resistance critical for long-term reliability in varied environmental conditions.

The dual diaphragm design amplifies braking force through two sealed pressure chambers, reducing pedal effort while maintaining proportional driver control. The 1-inch bore master cylinder is sized to optimize fluid displacement for the brake line volumes typical of these Mopar platforms. Dual integral reservoirs eliminate external reservoir plumbing, lowering overall weight and complexity while improving system packaging efficiency. This kit configuration—including booster, master cylinder, and necessary mounting hardware—delivers a complete brake system upgrade path for restoration projects or performance upgrades on classic Mopar muscle cars and body styles from this era.

Builders of Mopar B-Body, D-Body, and F-Body vehicles seeking modern brake response without radical conversion choose this assembly for its direct OEM fitment compatibility and engineering simplicity. The kit approach eliminates guesswork in component matching, reducing installation time and ensuring pressure balancing across front and rear circuits. At 22.95 lbs, the assembly weight supports weight distribution targets on vehicles where brake system mass matters. Whether restoring a 1970 Plymouth Road Runner or upgrading a Dodge Charger brake system, this LEED BRAKES master cylinder and booster kit addresses the core functional requirement: reliable, linear braking power with factory-grade integration.
