High-pressure die casting of a premium alloy produces a high-capacity body that is lightweight, looks great, and has the durability for competition that you expect from Wilwood Brakes. A black anodized, machined billet lid captures a pressure balanced bellows gasket with 100% sealing against moisture invasion or fluid leakage. The mounting flange is slotted to accommodate installation on bolt centers between 3.22" and 3.40". That makes it a simple bolt-on to many OE mounts including the popular Chrysler, Corvette, GM, and Ford Mustang master cylinder bolt patterns.

The body also features two through-hole mounts on 6.40" centers for side mounting to frame members or other secure elements of the chassis. Each master cylinder is configured with full separation between the front and rear reservoir chambers and fluid outlets. There is pressure access on both sides of the piston bore for right or left hand plumbing based on mount location. A total piston stroke of 1.10" is distributed at a 2:1 volume ratio between the primary and secondary chambers. A choice of 7/8", 1" or 1-1/8" bore sizes provides the necessary options to match the volume and pressure requirements of nearly any application. And for those wanting a show car look, a bright finish, media burnished version is available and guaranteed to catch the eye of the most discriminating enthusiasts.
