Rear Wheel Cylinder Cup Kit

About this product

The Rear Wheel Cylinder Cup Kit (#04906-20030), a crucial Drive-Chassis component in Toyota's Rear Drum Brake Wheel Cylinder & Backing Plate system, primarily facilitates efficient braking. As the brake pedal is pressed, brake fluid exerts pressure on the cups within the wheel cylinder, moving the brake shoes against the drum, resulting in deceleration or halting. Genuine Toyota parts like this enhance vehicle compatibility, backed by Toyota's genuine parts warranty. However, over time, cups may wear out, or fluid may leak, reducing brake effectiveness and potentially causing accidents. Therefore, periodic replacement is vital. By maintaining optimum brake performance, the Rear Wheel Cylinder Cup Kit (#04906-20030) contributes significantly to vehicle safety and efficiency.
