Wilwood High Volume Tandem M/C - 15/16in Bore Ball Burnished-W/Pushrod - Early Mustang

If you're upgrading the braking system on your 1964-1972 Ford Mustang, especially for a manual brake setup, a reliable master cylinder is key. This tandem master cylinder from Wilwood is built to handle the demands of a performance brake system, ensuring consistent fluid pressure to your wheels. It's designed to work with the factory brake pedal assembly, making installation more straightforward.

This master cylinder features a 15/16-inch bore, which is a common size for manual brake applications, and it's machined from high-pressure die-cast aluminum. This material choice makes it significantly lighter than stock cast iron units, weighing in at just 3 pounds, which is about a 75% weight savings. The tandem design means it has two separate fluid chambers for safety – if one circuit has an issue, the other can still provide some braking power. It also includes fluid outlet ports on both sides, giving you flexibility during installation. The stroke is set at 1.10 inches, with a 2:1 volume ratio between the primary and secondary chambers to help optimize brake feel.

Wilwood offers this master cylinder in a few finishes, and this particular model is ball burnished for a clean, classic look. It's designed to fit mount flanges between 3.22 and 3.40 inches, matching the factory manual master cylinder mount on 64-72 Mustangs. If you're looking to add a proportioning valve, Wilwood offers specific kits designed to work with this master cylinder.
