Description
The LF Series Hydraulic Master Kit solves the common problems that plague traditional hydraulic conversions in 1960-1972 Chevy and GMC full-size trucks and Blazers. Conventional setups force you to raise the master cylinder above the stock clutch rod hole, creating firewall interference and heavy pedal pressure. MDL's revolutionary linkage design maintains the factory rod location while delivering full mechanical advantage--giving you a light pedal effort and complete clutch control.
The Type 3 master cylinder utilizes a 0.750" small-bore with 1.4" long-stroke configuration, providing the fluid volume requirements needed for today's hydraulic slave cylinders. The innovative pedal linkage allows the full swing of the factory pedal to maximize clutch modulation while keeping the cylinder perpendicular to the firewall. This mechanical advantage drastically reduces pedal pressure while eliminating the firewall stress common with direct-mount designs. The linkage also provides clearance for brake boosters of all types.
The integral reservoir eliminates external fluid lines and remote mounting complexity, providing a clean, reliable installation. The system is engineered to work seamlessly with MDL LF Series external slaves, Tilton 6000 Series internal bearings, and most hydraulic release systems on the market. Use DOT 3 or DOT 4 brake fluid only--no high-temperature fluid required.
Compatible with 1960-1972 Chevrolet and GMC C10, C20, and full-size Blazer trucks using factory or OE reproduction clutch pedals. Proudly made in the USA with MDL's lifetime technical support.
