Failure Symptoms & Maintenance
When to Replace:
- Brake fluid leak at wheel
- Spongy or long-travel brake pedal
- Uneven braking or vehicle pull
- Brake fade or overheating drums
- Brake warning light illumination
Consequence of Ignoring Symptoms: Fluid loss, overheated drums, damaged brake components, and potential complete braking loss on one rear wheel - creating critical safety hazards for commercial vehicles.
Maintenance Schedule:
- Inspect wheel cylinders every 40,000-50,000 km
- Replace wheel cylinders in axle pairs
- Flush brake fluid every 2 years
- Inspect backing plate for fluid leaks during oil changes
