If your parking brake won’t release, it means the brake system is stuck in the engaged position. This can prevent the car from moving or cause the brakes to drag while driving, which may overheat and damage components. An inspection is required to free the system and restore safe operation.

What does it mean if the parking brake won’t release?

This usually indicates a problem with the brake cables, calipers, or the electronic parking brake system. Corrosion, seized parts, or electrical faults may stop the brake from disengaging.

Common causes of a parking brake that won’t release

• Seized or rusted parking brake cables
• Frozen or corroded brake calipers (disc brakes)
• Seized brake shoes or hardware (drum brakes)
• Faulty or jammed parking brake lever, pedal, or button
• Electronic parking brake actuator or module fault

Why do you need to fix this problem quickly?

A parking brake that won’t release can cause overheating, excessive wear, and reduced fuel efficiency. It may also leave the car undriveable, requiring towing if the brake cannot be freed.

How do you know when to get it checked?

You should book an inspection if:

• The parking brake lever, pedal, or button doesn’t release the brake
• The car struggles to move or won’t move at all
• You smell burning from overheated brakes
• You hear grinding, squealing, or dragging noises while driving
• The electronic parking brake warning light flashes or shows an error

What happens during an assessment?

A mechanic will:

1. Inspect the parking brake lever, pedal, or electronic actuator
2. Check the cables and linkage for seizure or rust
3. Inspect rear calipers or drums for sticking components
4. Lubricate or free seized parts if possible
5. Replace faulty cables, calipers, or electronic parts if required
6. Test the system to ensure proper release and engagement

How much does it cost to fix?

Freeing a stuck brake may cost $150–$300. Replacing parking brake cables typically costs $250–$600. If calipers, drums, or electronic actuators are faulty, costs may range from $400–$1,200+.

Is it unsafe to drive with a parking brake that won’t release?

Yes. Driving with the brake engaged causes overheating, severe brake wear, and reduced stopping ability. It can also damage the drivetrain. The car should not be driven until the issue is repaired.
