Every driver knows the importance of a functioning parking brake. It’s the safety net that keeps your vehicle from rolling away when parked on an incline or even on a flat surface. But how do you know for sure if your parking brake is engaged? Mistaking a disengaged brake for an engaged one can lead to a runaway car, causing damage and potential injury. Conversely, leaving the parking brake on when driving can damage your brakes and transmission. This comprehensive guide will walk you through the various ways to tell if your parking brake is on, ensuring you drive with confidence and peace of mind.

Understanding Your Parking Brake
Before we dive into the methods of checking, it’s essential to understand the different types of parking brakes and how they work. Most modern vehicles use either a mechanical parking brake or an electronic parking brake (EPB).
Mechanical Parking Brake
A mechanical parking brake uses a cable system to apply pressure to the rear brake drums or discs. This is often a hand lever located near the driver’s seat. Pulling the lever engages the brake, and releasing it disengages it.
Electronic Parking Brake (EPB)
An EPB is electronically controlled and often activated by a button on the center console. It uses electric motors to apply pressure to the brakes. Some EPBs also incorporate automatic engagement when the vehicle is turned off and can be released by pressing a button or using the accelerator pedal.
Signs Your Parking Brake Is On
Here are some telltale signs that your parking brake is engaged:
1. Physical Resistance
With a mechanical parking brake, you’ll feel resistance when you try to move the vehicle. The lever will be in an engaged position, and it will take effort to pull it up.
2. Brake Light Illumination
Many vehicles, especially those with EPBs, will illuminate the brake light on the dashboard when the parking brake is engaged. This serves as a visual reminder. (See Also: Where Is the Brake Fluid Reservoir Located? A Quick Guide)
3. Grinding or Squealing Noise
If you attempt to drive with the parking brake on, you’ll likely hear a grinding or squealing noise. This is because the brake pads are being forced against the rotors or drums, creating friction.
4. Difficulty Moving the Vehicle
The most obvious sign is that your vehicle won’t move easily. If you try to start the car or put it in gear and it feels stuck, the parking brake is likely engaged.
How to Check Your Parking Brake
Here’s a step-by-step guide to ensure your parking brake is properly engaged or disengaged:
1. Visual Inspection
For mechanical parking brakes, visually inspect the lever. It should be pulled up and locked in place. For EPBs, check the dashboard for the illuminated brake light indicator.
2. Feel the Resistance
Gently try to roll the vehicle forward or backward. If you feel resistance, the parking brake is engaged.
3. Listen for Noises
If you attempt to drive with the parking brake on, listen for any grinding or squealing noises. This indicates the brakes are being applied unnecessarily.
Important Considerations

1. Parking on an Incline
Always engage your parking brake when parking on an incline. This prevents your vehicle from rolling backward.
2. Using the Parking Brake While Driving
Never leave your parking brake engaged while driving. This can damage your brakes and transmission.
3. Regular Maintenance
Have your parking brake inspected and serviced regularly to ensure it functions properly. This can help prevent unexpected issues.
Recap: How to Tell if Your Parking Brake Is On
Knowing how to check your parking brake is crucial for safe driving. Understanding the different types of parking brakes, recognizing the signs of engagement, and following the proper inspection procedures can help you avoid accidents and damage to your vehicle. Remember, always engage your parking brake when parked on an incline and never leave it engaged while driving. Regular maintenance is also essential to ensure your parking brake remains reliable. By following these guidelines, you can drive with confidence knowing that your vehicle is secure.
Frequently Asked Questions
How do I know if my electronic parking brake is on?
Most vehicles with EPBs will have a visual indicator on the dashboard, usually a brake symbol with a “P” or a small parking brake icon, that illuminates when the EPB is engaged. Additionally, you’ll often feel a slight resistance when you try to move the vehicle forward or backward.
What happens if I drive with the parking brake on?
Driving with the parking brake engaged can cause significant damage to your vehicle. The brake pads will be constantly rubbing against the rotors or drums, generating excessive heat and potentially causing brake failure. It can also strain your transmission and engine.

Can I use my parking brake to slow down my car?
It’s generally not recommended to use your parking brake to slow down your car. It’s designed for parking and holding the vehicle stationary, not for regular braking. Using it for slowing down can overheat the brakes and potentially lead to failure.
How often should I service my parking brake?
It’s a good idea to have your parking brake inspected and serviced at least once a year, or as recommended by your vehicle’s manufacturer. This can help ensure it remains in good working order and prevent potential problems.
What should I do if my parking brake is stuck?
If your parking brake is stuck, do not force it. Instead, consult your vehicle’s owner’s manual for specific instructions on how to release it. If you’re unable to release it yourself, it’s best to have a qualified mechanic inspect and repair the issue.
