8in Dual Power Booster 1in Bore Master Zinc

The LEED Brakes 8-inch Dual Power Booster with 1-inch Bore Master Cylinder (Model C83) is a complete hydraulic brake system designed for classic Jeep platforms, specifically engineered for CJ5 and CJ7 models. This integrated master cylinder and booster assembly delivers the responsive brake modulation required in off-road and trail environments where consistent stopping power under variable load conditions is essential. The dual integral reservoir design eliminates external lines in the engine bay, reducing contamination risk and improving system reliability during extended field operations.

The dual diaphragm booster configuration provides proportional brake force multiplication, translating driver input into adequate stopping power without excessive pedal effort—critical when operating vehicles loaded with gear or towing recovery equipment. The 1-inch bore master cylinder is sized to deliver firm pedal feel while maintaining the leverage characteristics Jeep operators expect. Gold zinc plating on the steel construction resists corrosion from salt spray, mud exposure, and high-humidity environments common to coastal and wetland operations. The 8-inch outer diameter housing integrates into classic Jeep engine compartments without modification, preserving original mounting geometry and ensuring compatibility with existing brake line routing.

This assembly serves CJ5 models from 1976–1983 and CJ7 models from 1976–1986, making it the correct specification for frame-off restorations, fleet brake system upgrades, and vehicles returned to service after extended downtime. Operators performing their own brake service will appreciate the integrated design, which consolidates two major hydraulic components into a single installation point, reducing labor time and potential leak points. The kit format arrives with all necessary components for drop-in installation, provided original mounting brackets are intact.
