Dorman - First Stop Drum Brake Wheel Cylinder P/N:W3731
Give your rear drum brakes fresh seals and a tested bore with the Dorman First Stop drum brake wheel cylinder, part number W96402, a direct-fit replacement for the 1975-1980 Volkswagen Rabbit and 1975-1980 Volkswagen Scirocco. The wheel cylinder turns hydraulic pressure from the master cylinder into the force that pushes the brake shoes outward against the drum.
Dorman engineered this wheel cylinder to match the fit, function and performance of the original on the listed applications. Each unit is manufactured and tested for quality assurance.
Signs a wheel cylinder may need replacing include brake fluid seeping inside the drum or onto the backing plate, fluid-soaked brake shoes, a soft or low brake pedal, or the vehicle pulling to one side under braking. Diagnose the cause before replacing parts; if a leaking or sticking wheel cylinder is the problem, this unit replaces it. See the "Vehicles it fits" section for engine-level fitment details.
