Failure Symptoms
- Brake Fluid Leakage: Visible fluid seeping from rear wheels or inside brake drum
- Soft or Spongy Brake Pedal: Pedal feels unusually soft or goes to the floor
- Uneven Braking: Vehicle pulls to one side during braking
- Reduced Braking Performance: Longer stopping distance or increased pedal pressure
- Contaminated Brake Shoes: Brake fluid soaking into brake shoes causing reduced friction
Warning: A failing brake wheel cylinder can lead to reduced braking performance and potential brake failure. Prompt replacement is essential. For optimal performance, replace brake wheel cylinders in pairs (both rear wheels).
