The Wilwood 260-7563 Tandem Remote Master Cylinder is designed to provide one of the safest and most reliable methods for actuating four-wheel brake systems or dual-caliper axle configurations. Featuring a true 50/50 output from a 1.00-inch bore and 1.10-inch stroke, this tandem master cylinder ensures balanced hydraulic pressure delivery across dual brake circuits.
