Wheel Brake Cylinder Piston Sub-Assembly

About this product

The Wheel Brake Cylinder Piston Sub-Assembly (#47051-30030), a pivotal Drive-Chassis part in Toyota's Rear Drum Brake Wheel Cylinder & Backing Plate system, facilitates the braking action by directly applying force to the brake shoes. Functioning in close conjunction with hydraulic brake fluid, it exerts pressure on the brake shoes, pushing them against the drum to execute a successful halt. This component, however, is not immune to wear and tear. Aged, clogged, or damaged pistons can compromise your vehicle's braking efficiency, causing delayed or inadequate brake responses. Therefore, periodic replacements with genuine Toyota parts are recommended, not only for compatibility but also for the reassurance of Toyota's genuine parts warranty. In essence, the Wheel Brake Cylinder Piston Sub-Assembly (#47051-30030) significantly contributes to the overall safety of your vehicle, playing an integral role in its braking system's effectiveness.
