Compact Tandem Master for Classic Mustang - Product Summary

Wilwood’s Compact Tandem Master Cylinder for Mustangs comes with the correct pushrod; 4 bore sizes; 7/8" through 1-1/8th and is available in 2 finishes ball burnished, and black e-coat. These master cylinders are designed primarily for manual applications and include the correct pushrod for the factory 64-72 brake pedal. They’re designed for mount flanges from 3.22” to 3.40”, which match the 64-72 factory manual master cylinder mount, and offer fluid outlet ports on both sides of the bore. The stroke is set at 1.10” with a volume ratio of 2:1 between the primary and secondary chambers. Machined from high-pressure die castings, each master cylinder weighs only 3lbs, a 75% weight savings over most cast iron OE type master cylinders. We also offer a combination proportioning valve kit, which includes brackets and stainless lines specifically for use with this master cylinder, see retrofit kits PN 260-14248 for L/H outlets, or 260-15667 for R/H outlets.
