Description
Converting to hydraulic clutch actuation means tracking down a master cylinder, then hunting for the right fittings, pushrods, and hardware to make it work. This complete LF Series master cylinder kit bundles everything needed for the conversion, eliminating the parts-chasing headache and ensuring component compatibility from the start.
The 0.750-inch bore paired with a full 1.4-inch stroke generates 0.620 cubic inches of displacement volume per stroke - enough fluid movement to properly actuate most internal and external slave cylinders on the market. Don't confuse this with the shorter-stroke Wilwood GS compact masters that limit displacement. If your application doesn't require the full stroke, MDL also offers a 7/8-inch bore master for higher-volume applications.
The integral reservoir design keeps everything in one compact, self-contained unit. No remote reservoir mounting, no external lines between reservoir and cylinder - just a clean installation with fewer potential leak points. Every MDL hydraulic master kit is hand-assembled in-house where tolerances and quality are controlled directly. Each unit is tested and proven, then double-checked for fit and finish before it goes in the box.
This universal kit works with factory clutch pedals and OE reproduction aftermarket units. Standard DOT 3 or 4 brake fluid is all that's required - no expensive high-temp racing fluid necessary. The included one-man bleeder kit means you can get the air out solo, no assistant needed to pump the pedal. Made in the USA and backed by MDL technical support at 208-453-9800.
