Failure Symptoms & When to Replace
- Brake fluid leak at wheel: Visible wetness around backing plate or inside brake drum
- Spongy or long-travel brake pedal: Pedal sinks further than normal and feels soft
- Uneven braking or vehicle pull: Vehicle pulls to one side during braking
- Brake fade or overheating drums: Extended stopping distances and hot brake drums
- Brake warning light illumination: Dashboard brake warning activates
Consequence of Ignoring Symptoms: If left unreplaced, a leaking wheel cylinder can lead to fluid loss, overheated drums, damaged brake components, and complete loss of braking on one rear wheel.
