Dorman - First Stop Drum Brake Wheel Cylinder P/N:W37158
Turn hydraulic line pressure into the shoe-spreading force your rear drum brakes rely on with the Dorman - First Stop Drum Brake Wheel Cylinder (W131480). It installs as a direct-fit replacement for the 1995-2004 Toyota Tacoma [All] and the 2005-2023 Toyota Tacoma [All], mounting in the rear (rear right / rear left) drum-brake position. When brake fluid reaches the cylinder, its pistons push the brake shoes outward against the drum. A leaking or seized wheel cylinder is a common cause of a soft pedal, fluid on the backing plate, or uneven rear braking; if the original cylinder is the cause, this replaces it.
Quantity varies by application: the 1995-2004 Tacoma uses one, while the 2005-2023 Tacoma uses two. Package contains one cylinder — replacing both rear sides together as a matched pair is good practice for even braking. Country of origin: China.
