Wilwood High Volume Tandem Master Cylinder - 15/16in Bore Ball Burnished-W/Pushrod

This is a Wilwood High Volume Tandem Master Cylinder with a 15/16 inch bore, finished in ball burnished aluminum. It's designed primarily for manual brake applications and comes with a pushrod, ready to be installed. This master cylinder is built to fit common domestic car and truck mount flanges, typically found from the mid-1960s to today.

Wilwood machines these master cylinders from high-pressure die castings, resulting in a lightweight unit that weighs only 3 pounds. That's about a 75% weight savings compared to heavier cast iron master cylinders you might find on original equipment. It features fluid outlet ports on both sides of the bore, giving you flexibility during installation. The internal design includes a stroke set at 1.10 inches and a 2:1 volume ratio between the primary and secondary chambers, which helps ensure consistent braking performance.

For a complete brake system upgrade, Wilwood offers a combination proportioning valve kit that includes brackets and stainless steel lines specifically designed to work with this master cylinder. You can find these kits under part numbers 260-13190 or 220-13189.
