Wilwood Tandem Remote Master Cylinder - 1 1/8in Bore Black

If you're upgrading your braking system and need a reliable master cylinder for a power brake setup, this Wilwood Tandem Remote Master Cylinder is a solid choice. It's designed to work with either vacuum or hydraulic assist systems, making it versatile for many custom builds or restorations. The 1 1/8 inch bore size is specifically suited for power brake applications, ensuring you get the right amount of fluid displacement for your calipers.

Wilwood machines these master cylinders from high-pressure die castings, resulting in a part that's not only strong but also remarkably lightweight – about 3lbs, which is a 75% weight saving compared to typical cast iron master cylinders. This can be a notable advantage in performance builds where every pound counts. The design includes fluid outlet ports on both sides, offering flexibility during installation, and it features a fixed stroke of 1.12 inches with a 2:1 volume ratio between the primary and secondary chambers for consistent braking force.

This master cylinder is built to fit common domestic car and truck mount flanges from the mid-1960s to the present. For a complete setup, Wilwood also offers a combination proportioning valve kit (PN 260-14248) that includes brackets and stainless steel lines specifically designed to work with this master cylinder.
