Wilwood Aluminum Master Cylinder
Dual bowl, 15/16 inch bore, black e-coat finish with black lid. Designed for use with disc/drum or disc/disc brake systems, this 15/16 bore Wilwood tandem master cylinder is engineered primarily for manual brake applications and includes the correct pushrod for installation. The slightly larger 15/16 bore provides a firmer pedal feel compared to a 7/8 bore, while still maintaining excellent hydraulic leverage for manual systems. Machined from high-pressure die-cast aluminum, this lightweight unit weighs just 3 lbsapproximately 75% lighter than heavy cast-iron OE master cylinders. It fits standard 3.22″3.40″ mount flange spacing common to most mid-1960s and newer domestic vehicles, and features dual-side outlet ports for flexible brake-line routing. A 1.10 stroke and 2:1 chamber volume ratio ensure stable, consistent braking performance.
