Dorman - First Stop Drum Brake Wheel Cylinder P/N:W34043
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.
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.
