Common Causes of a Staying Hand Brake Light
The hand brake light can stay on due to various reasons, ranging from simple issues to complex problems. Here are some of the most common causes:
Loose or Faulty Parking Brake Cable
The parking brake cable connects the parking brake lever to the brake shoes. If the cable is loose or faulty, it can cause the hand brake light to stay on. Check the cable for any signs of wear or damage and tighten or replace it if necessary.
Worn-out or Damaged Brake Shoes
Brake shoes are designed to wear out over time, but excessive wear can cause the hand brake light to stay on. Inspect the brake shoes for any signs of wear or damage and replace them if necessary.
Clogged or Faulty Brake Master Cylinder
The brake master cylinder is responsible for distributing brake fluid to the brake shoes. If it’s clogged or faulty, it can cause the hand brake light to stay on. Have a professional mechanic inspect and clean or replace the master cylinder if necessary.
Faulty Brake Light Switch
The brake light switch is responsible for sending an electrical signal to the dashboard when the parking brake is engaged. If the switch is faulty, it can cause the hand brake light to stay on. Check the switch for any signs of wear or damage and replace it if necessary.
Incorrectly Adjusted Parking Brake
The parking brake should be adjusted properly to ensure it’s not applying excessive pressure to the brake shoes. If it’s not adjusted correctly, it can cause the hand brake light to stay on. Consult your vehicle’s owner’s manual for instructions on how to adjust the parking brake.
