Keep the rear drum brakes on your Toyota or Scion applying the way they should with the ADVICS Drum Brake Wheel Cylinder, MPN WCT-070. Fitted in the rear right position, this hydraulic cylinder receives pressurized brake fluid and pushes its pistons outward to force the brake shoes against the drum. It installs as a direct-fit replacement for the 2004-2006 Scion xB, 2003-2005 Toyota Celica, 2003-2008 Toyota Corolla, 2004-2009 Toyota Prius, and 2007-2018 Toyota Yaris — see the Buyer's Guide tab for engine-level fitment.
Signs the original wheel cylinder may need replacing include brake fluid seeping at the rear backing plate, a soft or sinking pedal, or uneven rear braking. If a leaking or seized wheel cylinder is the cause, this ADVICS unit replaces it. For balanced braking, it's best practice to service both sides of the axle together.
