Keep hydraulic pressure flowing to your drum brake shoes with the Dorman - First Stop Drum Brake Wheel Cylinder (W37284), a direct-fit replacement for the front right position on the 1964-1967 and 1968-1970 Volkswagen Transporter [All]. It was specifically engineered to match the original wheel cylinder's fit, function and performance, and is manufactured and tested for quality assurance.
Inside a drum brake, the wheel cylinder converts hydraulic brake-fluid pressure into the mechanical force that pushes the brake shoes outward against the drum. Replacing the cylinder while you service the drum brakes is a fast, sure way to help maintain consistent brake performance.
- Quality materials: built with high-quality EPDM rubber cups and boots for long-lasting performance.
- Cast iron body: with a 1 in inside-diameter bore.
- Professionally tested: the bore is surface-tested to provide an optimum sealing surface for the pressure cups.
- Ready to service: two M10 x 1.0 inlet threads with an included bleeder screw (bleeder screw cap not included).
If a leaking or seized wheel cylinder is behind a soft pedal, fluid seepage at the drum, or uneven drum braking, this replaces it. Country of origin: China.
