The parking brake is one of the most underused and underrated components in many vehicles. Also called the emergency brake or handbrake, it’s often seen as something you only use on a hill—or during an inspection. But just because you don’t use it often doesn’t mean you can ignore it. Like every other part of your braking system, your parking brake needs maintenance to stay reliable.
Here’s what you should know about how your parking brake works, why it matters, and how to keep it in top condition.
How the Parking Brake Works
The parking brake is a separate braking system from your main hydraulic brakes. It’s designed to hold your vehicle stationary when parked, especially on inclines. Depending on your car, it may use a cable connected to the rear brakes, an internal drum inside the rear rotor, or in newer vehicles, an electronic motor.
When you engage the parking brake, it applies mechanical force—usually via a cable or actuator—that locks the rear wheels in place. It’s a simple system, but like any other moving part, it can wear out or fail over time.
Common Issues With Parking Brakes
Just because your car stays put when you park doesn’t mean your parking brake is in great shape. Over time, components can corrode, cables can stretch, and moving parts can seize from lack of use. Some common problems include:
- Stuck brake: A parking brake that won’t release could be due to a rusted cable or frozen caliper.
- Loose lever or pedal: If you have to pull the handbrake way up or press the pedal all the way down, the cable may be stretched or the system is out of adjustment.
- No holding power: If your car still rolls when the brake is applied, there’s a serious issue that needs attention right away.
Moisture, salt, and general wear all contribute to parking brake problems—especially in vehicles that rarely use them.
Why You Should Use Your Parking Brake Regularly
Even on flat ground, using your parking brake helps keep the system functional. Letting it sit unused for months at a time can lead to corrosion, seized parts, and a stuck cable, especially in colder or wetter climates.
When used regularly, the mechanism stays lubricated and in motion, which helps prevent rust and ensures it’ll be there when you really need it—whether you're parked on a hill or in an emergency.
Electronic Parking Brakes Aren’t Maintenance-Free
Many modern vehicles come with an electronic parking brake, activated by a button rather than a lever or pedal. While convenient, these systems still rely on mechanical components that need to be checked during brake service.
If you’ve noticed your electronic brake takes longer to engage, makes unusual noises, or doesn’t fully hold, it may be due for inspection. Some systems also require special tools to retract or reset during brake pad changes, so it’s best to leave this service to trained technicians.
When to Get Your Parking Brake Inspected
Your parking brake should be checked at least once a year, ideally during your regular brake service. You should also have it looked at if:
- The brake feels weak or unresponsive
- You hear grinding, squealing, or scraping when using it
- Your vehicle rolls slightly even with the brake engaged
- It’s been more than a year since anyone inspected or adjusted it
A proper inspection includes checking the cable tension, looking for corrosion or damage, and making sure the system applies and releases as it should.
