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).

  • Cast-iron construction: cast-iron body with a 0.75 in bore.
  • EPDM cups and boots: made with high-quality EPDM rubber cups and boots for long-lasting performance.
  • Bleeder screw included: ships with a bleeder screw (a bleeder screw cap is not included).
  • Surface-tested bore: the wheel cylinder bore is surface-tested to help ensure an optimal sealing surface for the pressure cups.

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.
