- Brake Pedal: Engages or disengages the parking brake.
- Brake Actuator: The mechanism that physically engages the brake when the pedal is released.
- Brake Shoes/Pads: Contact the drum or disc to hold the machine stationary.
- Parking Brake Lever or Switch: In some models, an additional lever or switch may control the brake.
Common Symptoms of Parking Brake Problems
Understanding the symptoms of parking brake failure is the first step in diagnosing the issue. The following are common signs that the parking brake system may not be functioning correctly:
- Parking Brake Not Engaging
- The parking brake pedal or lever does not seem to hold the machine in place.
- The machine slowly drifts when parked on an incline or uneven surface.
- The parking brake pedal or lever does not seem to hold the machine in place.
- Excessive Pedal Travel
- The brake pedal feels spongy or has an unusually long range of motion before the brake engages.
- This could indicate air in the brake lines or worn-out brake components.
