Turn brake-line pressure into the shoe-spreading force that sets your drum brakes with the Dorman - First Stop Drum Brake Wheel Cylinder (MPN W37858). This rear-left drum brake wheel cylinder is a hydraulic actuator that converts brake-fluid pressure into outward force, pushing the shoes against the drum. It drops in as a direct-fit replacement for the 1991-2002 Honda Accord [All] and 1997-2001 Honda CR-V [All], and Dorman engineers it to match the fit, function and performance of the original cylinder on the listed applications.

  • Aluminum body: built around a 0.813 in inside-diameter bore that is surface-tested for an optimum sealing surface for the pressure cups.
  • EPDM rubber cups and boots: made with high-quality EPDM rubber for long-lasting sealing.
  • Bleeder screw included: comes with the bleeder screw for servicing (bleeder screw cap not included).
  • M10 x 1.0 inlet thread: a 10 mm thread with a 1.0 pitch for the brake-line connection.

If a leaking or seized wheel cylinder is behind a soft pedal or uneven rear braking, this replaces it during a drum service. Country of origin: China.
