Failure Symptoms & Replacement Indicators
- 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
⚠️ Ignoring these symptoms can lead to fluid loss, damaged brake components, and complete braking loss on one rear wheel - creating a critical safety hazard for loaded commercial vehicles.
