Dorman - First Stop Drum Brake Wheel Cylinder P/N:W3677
Send firm hydraulic pressure to the rear brake shoes with the Dorman - First Stop Drum Brake Wheel Cylinder W370027. Mounted in the rear drum brake, it converts the hydraulic pressure from the master cylinder into the mechanical force that pushes the shoes outward against the drum. It drops in as a direct-fit rear replacement for the 1996-1999 Chrysler Town & Country, 1996-1997 Chrysler Voyager, 1996-1999 Dodge Caravan and Grand Caravan, and 1996-1999 Plymouth Grand Voyager and Voyager (all engines).
Engineered to match the original wheel cylinder's fit, function, and performance on the listed applications, it's a cost-effective repair to make while servicing the drum brakes. The listed applications use two per vehicle — one per rear wheel — and this listing is for a single cylinder; order two and replace both sides together as a matched pair for even, balanced braking. Country of origin: China. Signs a wheel cylinder may need replacing include brake fluid leaking behind the drum, a soft or sinking pedal, and uneven rear braking.
