Description
If you’re running large-displacement brake calipers or need extra fluid capacity for high-heat racing applications, undersized master cylinders will leave you with mushy pedal feel and inconsistent braking pressure. The Wilwood 7/8-inch High-Volume Master Cylinder delivers 26% more reservoir capacity than comparable integral designs, ensuring your brake system maintains full pressure under sustained cornering and heavy deceleration. With 1.430 inches of piston stroke, you get the margin necessary to reliably actuate large-piston calipers without sacrificing pedal modulation.
Built from high-grade aluminum with a natural finish, this master cylinder is engineered for serious track use and street applications where reliability matters. The bellows-type gasket on the steel reservoir lid seals out moisture and contaminants that degrade brake fluid performance over time. Bolt-on or side-mount installation works with standard 1/8-27 NPT outlets, making integration straightforward on custom and stock brake setups alike.
