What does service parking brake mean on a Chevy Traverse?
The service parking brake, also known as the foot parking brake, is a crucial safety feature in the Chevy Traverse. It is designed to hold the vehicle in place when parked, preventing it from rolling away. This article will provide a detailed explanation of what the service parking brake is and how it functions in the Chevy Traverse.
What is the Service Parking Brake?
The service parking brake, or foot parking brake, is a mechanical brake system that is separate from the vehicle's main braking system. It is typically operated by a pedal or lever located near the driver's seat, which the driver can press or pull to engage the brake. When engaged, the service parking brake applies pressure to the rear wheels, holding the vehicle in place even when the main brakes are not in use.
In the Chevy Traverse, the service parking brake is designed to be used when the vehicle is parked, either on a flat surface or on an incline. It is an important safety feature that helps prevent the vehicle from rolling away, which could potentially cause damage or injury.
How Does the Service Parking Brake Work?
The service parking brake in the Chevy Traverse works by applying pressure to the rear brake drums or discs, similar to the main braking system. When the driver engages the parking brake, either by pressing a pedal or pulling a lever, a cable or hydraulic system transmits the force to the rear brakes, causing them to grip the wheels and hold the vehicle in place.
The service parking brake is designed to be used in addition to the main braking system, not as a replacement. It is important to always engage the parking brake when the vehicle is parked, even if the main brakes are also applied.
When Should the Service Parking Brake Be Used?
The service parking brake should be used in the following situations:
- When the vehicle is parked on a flat surface or incline
- When the vehicle is stopped and the driver is exiting the vehicle
- When the vehicle is being towed or transported on a trailer
- In emergency situations, such as if the main braking system fails
It is important to note that the service parking brake should not be used while the vehicle is in motion, as this could cause the rear wheels to lock up and lead to a loss of control.
Maintaining the Service Parking Brake
To ensure the service parking brake in the Chevy Traverse continues to function properly, it is important to have it inspected and serviced regularly by a qualified mechanic. This may include adjusting the cable tension, replacing worn brake components, or lubricating the moving parts.
By understanding the purpose and proper use of the service parking brake, Chevy Traverse owners can help ensure the safety and reliability of their vehicle.
Can you drive with a service parking brake on?
Yes, you can drive in park brake maintenance mode, but it is generally not recommended except in an emergency. While driving in maintenance mode may be acceptable on some vehicles, it can lead to dangerous situations such as a complete lack of rear braking, which can cause the front brakes to overheat and fail, leading to loss of control. You should always follow the vehicle's manual to exit maintenance mode before driving to avoid these risks.
Risks of driving in maintenance mode
- Loss of braking: The rear brakes may not work at all, putting all the workload on the front brakes. This can cause them to overheat and fail.
- Damage to the brake system: Improperly using the maintenance mode can damage the brake caliper and other components, leading to expensive repairs.
- Brake fade: Excessive heat from the brakes can cause brake fade, making it more difficult to stop the vehicle.
- Warning indicators: The warning light may continue to flash, and an audible alarm may sound, even if the parking brake is not engaged.
What to do instead
- Follow your vehicle's manual: Always refer to your owner's manual for the correct procedure to exit maintenance mode before driving.
- Seek professional help: If you cannot exit maintenance mode, take your vehicle to a qualified mechanic for diagnosis and repair.
- Do not delay repairs: A faulty parking brake can lead to more serious problems down the road, so it's important to address the issue promptly.
What is the service parking brake on a Chevy Traverse?
A "service parking brake" warning on a Chevy Traverse indicates a problem with the electronic parking brake (EPB) system, and common causes include a faulty EPB switch, wiring issues, low brake fluid, worn brake pads, or a malfunctioning brake control module. To diagnose the issue, first check the brake fluid level and inspect the EPB switch and wiring for damage or corrosion. If the problem persists, use an OBD-II scanner to read the error codes and potentially reset the system after repairs are completed.
Possible causes
- Faulty EPB switch or wiring: The switch that engages/disengages the parking brake can malfunction, or the wiring harness can become damaged or corroded.
- Low brake fluid: A low brake fluid level can trigger a warning light for the brake system in general.
- Worn brake pads: Severely worn brake pads can cause the EPB system to malfunction.
- Electronic brake control module (EBCM) or actuator issues: The module that controls the parking brake or the actuators at each wheel can fail.
- Faulty wheel speed sensors: Problems with the wheel speed sensors can sometimes trigger the warning light.
How to troubleshoot
- Check brake fluid: Verify the brake fluid level in the master cylinder. If it's low, add the correct type of fluid and check for leaks.
- Inspect the EPB switch and wiring: Look for any visible damage, corrosion, or loose connections on the switch and the wiring that runs to it and the rear calipers.
- Examine brake components: Check the condition of your brake pads and rotors. While less common for the EPB light, they are a critical part of the overall system.
- Use a diagnostic scan tool: An OBD-II scanner can read specific diagnostic trouble codes (DTCs) from the EPB module, which will provide a more precise diagnosis.
- Reset the system: After addressing any issues, a scan tool may be required to clear the warning light and reset the system.
