Brakes

Parking brake won't release

When the parking brake stays engaged even after releasing the lever, pedal, or button, it's usually a stuck cable or, on electronic parking brakes, a switch or motor fault, and driving with it engaged can overheat the rear brakes.

Symptoms

  • Parking brake indicator light stays on after attempting to release it
  • Car feels like it's dragging or resisting movement
  • Possible burning smell from the rear brakes if driven

Likely causes

  • CommonFrozen or corroded parking brake cableCables can seize, especially in cold, wet, or salty conditions, or after long periods unused.
  • CommonRust buildup on rear brake components (drums or rotors) from sittingCommon after a car sits for an extended time without being driven.
  • PossibleFaulty electronic parking brake switch or motorOn cars with a button instead of a lever, an electronic fault can prevent release.
  • Less commonStuck parking brake lever mechanismMechanical wear or debris in the lever assembly itself.

What to do

  1. Try releasing the parking brake several times, using more force on a manual lever if it feels stuck.
  2. On electronic parking brakes, check the owner's manual for an emergency manual release procedure.
  3. Rock the car gently forward and backward while attempting to release, which can sometimes free a stuck cable.
  4. Do not force the car to move if the rear wheels are clearly locked, since this can damage brake components.
  5. If it releases but felt very stiff, have the cable inspected and lubricated soon before it happens again.
  6. Have a mechanic replace a seized cable or repair a faulty electronic parking brake motor/switch.
  7. Avoid using the parking brake in freezing rain or ice storms if it has a history of sticking, until repaired.

When to call a pro

See a mechanic if the parking brake won't release with normal effort, especially before driving any distance.

Safety

Use caution

Do not force the car to move if a rear wheel is fully locked by a stuck parking brake; this can damage the brake and cause loss of control.
