What is the Park Brake?
The park brake, also known as the emergency brake or handbrake, is a crucial safety system in all vehicles. Its primary function is to prevent the vehicle from rolling when parked on an incline or flat surface. Unlike the service brake, which is used for slowing down and stopping the vehicle while driving, the park brake engages a separate braking mechanism that locks the wheels in place.
How Does the Park Brake Work?
The park brake typically operates by engaging a cable or hydraulic system that applies pressure to the rear wheels’ brake drums or calipers. This pressure prevents the wheels from turning, effectively immobilizing the vehicle.
Types of Park Brakes
There are two main types of park brakes:
- Mechanical Park Brakes: These systems utilize a hand lever or knob that pulls a cable connected to the rear brakes.
- Hydraulic Park Brakes: These systems use hydraulic fluid pressure to activate the rear brakes.

- You Manually Engaged the Park Brake: The most common reason is that you intentionally activated the park brake when parking your vehicle.

- Seek Professional Assistance: If the message continues to appear or you suspect a malfunction, consult a qualified mechanic for diagnosis and repair.
Safety Precautions When Using the Park Brake
While the park brake is a vital safety feature, it’s essential to use it correctly to avoid potential damage or accidents.
- Engage the Park Brake on Slopes: Always engage the park brake when parking on an incline to prevent the vehicle from rolling backward.
- Release the Park Brake Before Driving: Ensure that the park brake is fully released before starting to drive.

Possible Causes:
- Faulty Park Brake Switch: The park brake switch, which signals the vehicle’s computer that the park brake is engaged, may be malfunctioning.
- Worn Brake Cables or Lines: Over time, brake cables or hydraulic lines can wear out, leading to improper engagement or release of the park brake.
- Mechanical Issues with the Park Brake Mechanism: There may be mechanical problems within the park brake mechanism itself, such as a seized caliper or drum.
Diagnostic Steps:
- Check for Obstructions: Ensure that nothing is obstructing the park brake lever or knob.
- Inspect the Park Brake Switch: If equipped with a mechanical park brake, inspect the switch for signs of wear or damage.
- Test the Park Brake System: Engage and release the park brake several times to ensure it operates smoothly.
