Alum. Tandem M/C Kit w/ Brkt Prop Valve 15/16in

The Wilwood Aluminum Tandem Master Cylinder Kit with Bracket Proportioning Valve (Model 261-14158-BK) is a complete hydraulic brake system component designed for custom and high-performance vehicle applications. This tandem master cylinder kit combines proven engineering with an integrated proportioning valve and mounting bracket, eliminating the need for separate component sourcing and reducing installation complexity on brake system builds.

The unit features a 0.938-inch bore diameter and 1.100-inch stroke length, engineered to deliver consistent hydraulic pressure modulation across front and rear brake circuits. The aluminum construction with black powder-coat finish provides corrosion resistance in harsh driving environments—particularly valuable for vehicles exposed to road salt or coastal moisture. The integral reservoir eliminates external tank plumbing and streamlines underhood packaging, while the included proportioning valve ensures balanced braking force distribution, a critical safety requirement in both street and track applications.

This kit serves builders and restoration specialists working on custom hot rods, classic car restorations, and performance brake system upgrades where factory hydraulic architecture cannot meet modern stopping demands. The factory-matched bracket design simplifies fitment and reduces fabrication labor. The proportioning valve's integration prevents brake lock-up on the rear axle during aggressive deceleration, a fundamental requirement for safe dual-circuit braking that meets DOT standards.

Wilwood's tandem master cylinders are industry standard in the custom automotive and racing communities, where reliability under repeated high-G braking events is non-negotiable. This complete kit minimizes assembly time on brake system projects by consolidating master cylinder, valve, and bracket into a single verified assembly.
