Keep the rear drum brakes on your Toyota firm and responsive with the ADVICS Drum Brake Wheel Cylinder WCT-027. Mounted inside the rear brake drum, this wheel cylinder uses hydraulic pressure from the brake system to push its pistons outward and press the brake shoes against the drum. It installs as a direct-fit replacement for the rear position on the 1988-1989 and 1992-1995 Toyota 4Runner, 1988 Toyota Pickup, and 1993-1998 Toyota T100 — see the Buyer's Guide tab for engine-level details.
Signs the original wheel cylinder may need replacing include brake fluid leaking at the backing plate, a soft or sinking brake pedal, or weak, uneven rear braking. Replacing a leaking or seized wheel cylinder helps restore proper hydraulic actuation of the rear brake shoes.
