Dorman - First Stop Drum Brake Wheel Cylinder P/N:W3677
Convert hydraulic pressure into shoe-to-drum force with the Dorman - First Stop Drum Brake Wheel Cylinder W93083. This rear-position drum brake wheel cylinder drops in as a direct-fit replacement for the 1955-1971 Volkswagen Transporter (All), where two are used per vehicle — order 2 to service both rear wheels. Dorman engineered it to line up with the original cylinder's fit, function, and performance on the listed applications, and it is manufactured and tested for quality assurance.
Replacing the wheel cylinder while you service the rear drums is a fast, cost-effective way to help keep the hydraulic side of the brakes working properly. If a leaking or seized cylinder is the cause of a soft pedal, fluid behind the drum, or uneven braking, this replaces it. Country of origin: Taiwan.
