Quick notes
- It is a mechanism that locks the rear wheels in place, ensuring that the vehicle remains stationary even on slopes or uneven surfaces.
- Engaging the parking brake control reduces stress on the transmission and other components, as it eliminates the need to rely solely on the parking gear to hold the vehicle in place.
- Some modern vehicles feature automatic parking brake control, which engages the parking brake automatically when the vehicle is put in park.
Parking brake control is a crucial safety feature in modern vehicles, designed to prevent unintended vehicle movement when parked. It is a mechanism that locks the rear wheels in place, ensuring that the vehicle remains stationary even on slopes or uneven surfaces.
Importance of Parking Brake Control
Parking brake control plays a vital role in preventing accidents and ensuring the safety of both the vehicle and its occupants. Here are some of its key benefits:
- Prevents Unintended Rolling: Parking brake control prevents the vehicle from rolling away when parked, even if the transmission is in gear. This is especially important on slopes or inclines, where the force of gravity can cause the vehicle to move.
- Enhances Stability: When engaged, the parking brake control locks the rear wheels, enhancing the vehicle’s stability. This is particularly beneficial in slippery or icy conditions, where traction can be compromised.
- Reduces Wear and Tear: Engaging the parking brake control reduces stress on the transmission and other components, as it eliminates the need to rely solely on the parking gear to hold the vehicle in place.
- Improves Brake Life: Parking brake control helps extend the life of the regular brakes by preventing them from being used for extended periods when the vehicle is parked.
Types of Parking Brake Control
There are two main types of parking brake control systems:
- Mechanical Parking Brake: This traditional system uses a lever or pedal that mechanically engages the rear brake pads against the rotors.
- Electronic Parking Brake (EPB): EPB systems use electric motors to actuate the parking brake, providing greater convenience and automation.
Operation of Parking Brake Control
Mechanical Parking Brake:
1. Pull up the lever or depress the pedal to engage the parking brake.
2. A cable or rod connects the lever/pedal to the rear brake calipers.
3. The cable/rod pulls the brake pads into contact with the rotors, locking the rear wheels.
Electronic Parking Brake:
1. Press the EPB button or switch on the dashboard.
2. An electric motor is activated, which engages the rear brake calipers.
3. The motor applies pressure to the brake pads, locking the rear wheels.
Automatic Parking Brake Control
Some modern vehicles feature automatic parking brake control, which engages the parking brake automatically when the vehicle is put in park. This eliminates the need for manual activation and provides an additional layer of safety.
Disengaging Parking Brake Control
To disengage the parking brake control:
Mechanical Parking Brake:
1. Release the lever or pedal.
2. The cable/rod retracts, releasing the brake pads from the rotors.
Electronic Parking Brake:
1. Press the EPB button or switch on the dashboard again.
2. The electric motor releases the brake calipers, disengaging the rear wheels.
Troubleshooting Parking Brake Control Issues
If you encounter any issues with your parking brake control, here are some troubleshooting tips:
- Mechanical Parking Brake: Check the cable/rod for damage or corrosion. Ensure that the brake pads are not worn or contaminated.
- Electronic Parking Brake: Consult the vehicle’s owner’s manual for specific troubleshooting steps. It may involve checking electrical connections or resetting the EPB system.
