Product Description

The Wilwood 261-14963-BK Compact Tandem Master Cylinder Kit is a universal high-performance brake master cylinder solution that combines a compact tandem chamber body with a built-in combination proportioning valve and mounting bracket. The 1.00" bore and integrated dual chamber reservoir help deliver strong hydraulic pressure and balanced fluid volume for a variety of brake system applications.
