The Wilwood 261-15523-BK Compact Tandem Master Cylinder is designed for Mustang brake system applications requiring dependable hydraulic control and an integrated proportioning solution. Its compact design combines a tandem master cylinder with an integral fluid reservoir and included proportioning valve, helping simplify installation while supporting balanced front-to-rear brake performance. The 0.938-inch bore and 1.100-inch stroke provide a practical configuration for performance-oriented brake systems and custom installations.
Finished in black paint, the aluminum housing offers a durable and clean appearance suitable for street, competition, and restoration projects. The integral reservoir reduces the need for a separate remote reservoir in compatible applications, helping maintain a streamlined engine compartment and simplified plumbing. The included proportioning valve allows brake bias to be adjusted for changing vehicle setup, tire, and driving conditions when installed and configured correctly.
This Wilwood master cylinder kit is supplied as a complete assembly for applications that call for a compact tandem unit with proportioning capability. Verify mounting requirements, pedal linkage, outlet configuration, fluid compatibility, and vehicle-specific clearance before installation. Professional installation and proper brake bleeding are recommended to ensure reliable hydraulic operation. Use the Wilwood 261-15523-BK as a focused upgrade or replacement component when a black-finished aluminum master cylinder with an integral reservoir and included proportioning valve meets the requirements of the brake system.
