Description

The Wilwood 261-13270-BK is a comprehensive aluminum tandem master cylinder kit, engineered to provide precise brake pressure actuation and fluid control. This kit includes the master cylinder, a combination proportioning valve, a mounting bracket, fluid tubes, and all necessary mounting hardware, simplifying custom brake system installations. The tandem master cylinder itself is constructed from aluminum and finished in a black E-coat for enhanced durability and a performance look. It features an integral reservoir with dual capacity options (8.0 oz / 4.8 oz or 14.4 cu in / 8.7 cu in) and a 1-1/8" bore size with a 1.100" stroke. The design of this master cylinder kit offers significant advantages for custom builds. Its slotted flange mounting allows for a straightforward bolt-on application to many original equipment (OE) mountings, commonly found on Chrysler, Corvette, GM, and Ford Mustang vehicles. This integration is crucial for custom systems where precise control is paramount. Installation is further simplified by the included components. Stainless steel fluid tubes are pre-bent and come with plated steel tube nuts, ensuring a simple connection between the proportioning valve and the master cylinder. The black E-coat finish on the valve and bracket provides a cohesive, performance-oriented appearance and protects against corrosion. Stainless steel button head fasteners are used for assembly, ensuring a durable, rust-free installation.
