Wilwood 261-13270 Tandem Master Cylinder Kit with Bracket and Proportioning Valve

The Wilwood 261-13270 tandem master cylinder kit is designed for performance braking systems that require dependable hydraulic control and a compact, service-friendly configuration. It features a 1.125-inch bore and 1.100-inch stroke to provide responsive pedal operation and consistent brake fluid displacement. The aluminum construction has a natural finish for a clean appearance and durable performance in demanding automotive applications.
The integral reservoir simplifies installation by combining fluid storage with the master cylinder assembly, while the included mounting bracket helps support a secure and organized installation. A proportioning valve is also included to help fine-tune front-to-rear brake bias for improved control and balanced braking performance. This kit is well suited for custom builds, racing applications, and high-performance street vehicles where precise brake system setup is important.
Designed as a tandem master cylinder assembly, the Wilwood 261-13270 provides independent hydraulic circuits for enhanced braking-system reliability. Its carefully matched components make it a practical choice for builders replacing or upgrading a manual hydraulic brake system. Verify bore size, mounting requirements, pedal ratio, fluid compatibility, and vehicle application before installation to ensure proper system operation. The kit is not air restricted and is not designated for truck freight shipment.
