Wilwood Aluminum Master Cylinder
Dual bowl, 7/8 inch bore, ball burnished / polished finish with black lid. Engineered for disc/drum or disc/disc brake systems, this master cylinder is optimized for manual brake applications and includes the required pushrod. The 7/8 bore provides increased hydraulic leverage, delivering reduced pedal effort and improved modulationideal for non-boosted systems. Its high-pressure die-cast aluminum construction keeps weight to just 3 lbs, offering a dramatic 75% reduction compared to heavy cast-iron OE units. Designed to fit 3.22″3.40″ mount flanges common across many mid-1960s and later domestic vehicles, it also features fluid outlet ports on both sides for flexible brake line routing. A 1.10 stroke and 2:1 primary-to-secondary chamber volume ratio ensure smooth, balanced, and predictable braking performance.
