Wilwood Tandem Remote Master Cylinder - 7/8in Bore Ball Burnished

This is the Wilwood Tandem Remote Master Cylinder with a 7/8-inch bore, finished in ball burnished aluminum. It's built for custom brake systems where you need reliable hydraulic control. The tandem design means it has two separate fluid chambers, one for the front brakes and one for the rear, so if one circuit has an issue, the other can still function. This is a key safety feature for any custom build.

Wilwood machines these from high-pressure die castings, making them surprisingly light at only 3 pounds. That's a significant weight saving compared to heavier cast iron master cylinders you might find on older vehicles. The mount flange fits common measurements found on most domestic cars and trucks from the mid-1960s up to today, typically between 3.22 and 3.40 inches. It also features fluid outlet ports on both sides, giving you flexibility when routing your brake lines. The internal stroke is set at 1.12 inches, with a 2:1 volume ratio between the primary and secondary chambers to ensure consistent braking pressure.

If you're building a custom brake setup or upgrading an older system, this master cylinder is a solid option. Wilwood also offers a combination proportioning valve kit (PN 260-14248) with brackets and stainless lines that are specifically designed to work with these master cylinders, making installation more straightforward.
