What a parking brake handle does
Your parking brake handle is the lever, pedal, or button that locks your vehicle's rear wheels in place when you park. It keeps your car from rolling if you're on a slope, if the regular brakes fail, or if someone bumps into you. Unlike your foot brake, which you use while driving, the parking brake stays engaged until you deliberately release it — which is why it's sometimes called the emergency brake or hand brake.
The parking brake is a separate system from your main brakes. It connects directly to the rear wheels through cables or a hydraulic line, depending on your vehicle's age and make. When you pull or press the handle, you're tightening that connection. When you release it, the wheels are free to turn again.
Key Takeaways
- The parking brake locks your rear wheels and prevents your car from rolling, especially on hills or in parking lots.
- You should engage the parking brake every time you park, even on flat ground, to protect against unexpected movement.
- Different vehicles have different parking brake styles — a handle you pull, a pedal you press, or a button you push — but they all do the same job.
- If your parking brake feels loose, won't hold, or makes noise, it needs inspection because a failing brake can let your car roll into traffic or property.
- Leaving the parking brake on while driving can damage the brake system and cause your car to overheat.
Where the parking brake handle is located
The location depends on your vehicle's design. In most cars, the parking brake handle is between the front seats, either as a lever you pull up toward you or a pedal at the bottom left of the dashboard (to the left of the regular brake pedal). Some newer vehicles have a button or switch on the dashboard or steering column that you press to engage or release the brake electronically.
Check your owner's manual if you're unsure where yours is. The manual will also tell you whether your vehicle uses a traditional mechanical brake or an electronic one, which matters if something goes wrong.
How to use the parking brake correctly
Every time you park your car, engage the parking brake after you've come to a complete stop. If you have a pull handle, pull it toward you firmly until you feel resistance. If you have a pedal, press it down with your foot. If you have a button, press it once to engage and once more to release.
You should use the parking brake even on flat ground. It takes pressure off your transmission and reduces wear on your regular brakes. When you're ready to drive again, release the brake before you start moving. If you forget and try to drive with the parking brake on, you'll feel resistance and may hear a grinding sound — stop when ready and release it.
Signs your parking brake handle needs repair
If the handle feels loose or spongy when you pull it, if it doesn't hold your car on a slope, or if your car rolls slightly after you've engaged it, the brake system needs inspection. A mechanic can check whether the problem is a worn cable, a hydraulic leak, or a problem with the brake pads themselves.
Grinding, squeaking, or clicking sounds when you engage the brake also signal a problem. Don't ignore these signs — a failing parking brake can let your vehicle roll into traffic, a building, or another car, which creates both safety and legal liability for you.
Parking brake and parking violations
In some places, leaving your parking brake disengaged while parked can contribute to a parking violation if your car rolls and hits another vehicle or property. More importantly, it shows negligence if your car causes damage or injury. Always engage the parking brake as part of your parking routine.
If your car rolled and caused damage, and you can show that your parking brake was engaged and functioning, that strengthens your position if the other party tries to hold you responsible. Conversely, if your brake failed and you didn't maintain it, you may be liable for damage your car caused.
Maintenance and when to have it checked
Your parking brake doesn't need regular maintenance the way your engine does, but it should be inspected during your annual vehicle inspection or whenever you notice a change in how it feels or sounds. If you drive in hilly terrain regularly, or if you park on slopes, have the brake checked more often because it works harder.
If you have an older vehicle with a cable-based parking brake, the cables can rust or fray over time, especially in areas with road salt. A mechanic can replace them if needed. Electronic parking brakes in newer vehicles are generally more reliable but require a diagnostic tool if something goes wrong, so take those to a dealer or specialist.
Frequently Asked Questions
Can I drive with the parking brake on by accident?
Yes, and it happens often. You'll feel resistance and hear grinding or squeaking. Stop as soon as it's safe, release the brake, and check that it's fully disengaged before driving again. Driving with the brake on for a long distance can overheat the brake system and cause damage.
What if my parking brake handle broke off?
If it's a pull handle, you may be able to pull the cable directly until you can have it repaired, though this is uncomfortable and not a permanent fix. If it's electronic, you'll need a mechanic to diagnose the problem. Don't park your car on a slope without a functioning brake — use wheel chocks or park on flat ground instead.
Does the parking brake wear out faster if I use it every time I park?
No. Using the parking brake every time actually extends the life of your regular brakes by reducing wear on them. The parking brake is designed to be used constantly, so regular use is normal and expected.
Why does my parking brake feel different in winter?
Cold weather can make brake cables stiffer and hydraulic fluid thicker, so the brake may feel harder to engage or release. This usually goes away as the car warms up. If the problem persists or gets worse, have the brake inspected for rust or corrosion in the cable.
