Common Causes of Parking Brake Light Staying On
The parking brake light staying on can be caused by a variety of factors, ranging from simple misalignments to more complex mechanical issues. Here are some of the most common causes:
1. Misaligned Parking Brake Cable
One of the most common causes of the parking brake light staying on is a misaligned parking brake cable. The parking brake cable is responsible for transmitting the force of the parking brake to the brake shoes or pads. If the cable is misaligned, it can cause the parking brake to stay engaged, even when it’s released. To resolve this issue, you’ll need to adjust the parking brake cable to ensure it’s properly aligned.
2. Worn-Out Parking Brake Shoes or Pads
Worn-out parking brake shoes or pads can also cause the parking brake light to stay on. Over time, the parking brake shoes or pads can wear down, causing the parking brake to stay engaged. Replacing the worn-out shoes or pads can resolve this issue.
3. Faulty Parking Brake Switch
A faulty parking brake switch can also cause the parking brake light to stay on. The parking brake switch is responsible for sending a signal to the dashboard to illuminate the parking brake light. If the switch is faulty, it may send a false signal, causing the light to stay on even when the parking brake is released. Replacing the faulty switch can resolve this issue.
4. Low Brake Fluid Level
A low brake fluid level can also cause the parking brake light to stay on. If the brake fluid level is low, it can cause the parking brake to stay engaged, even when it’s released. Checking and topping off the brake fluid level can resolve this issue.
5. Faulty Brake Master Cylinder
A faulty brake master cylinder can also cause the parking brake light to stay on. The brake master cylinder is responsible for distributing brake fluid to the brake calipers. If the master cylinder is faulty, it can cause the parking brake to stay engaged, even when it’s released. Replacing the faulty master cylinder can resolve this issue.

Step 2: Check the Parking Brake Cable
Next, check the parking brake cable to see if it’s misaligned or damaged. You can do this by looking for signs of wear or damage on the cable, or by using a wrench to adjust the cable.
Step 3: Check the Parking Brake Shoes or Pads
Check the parking brake shoes or pads to see if they’re worn out or damaged. You can do this by looking for signs of wear or damage on the shoes or pads, or by using a wrench to adjust the shoes or pads.
Step 4: Check the Parking Brake Switch
Check the parking brake switch to see if it’s faulty. You can do this by using a multimeter to test the switch, or by replacing the switch if it’s faulty.
Step 5: Check the Brake Fluid Level
Check the brake fluid level to see if it’s low. You can do this by looking for the brake fluid reservoir under the hood, or by using a dipstick to check the fluid level.
Step 6: Consult a Professional Mechanic
If you’re unable to diagnose and resolve the issue on your own, it’s recommended to consult a professional mechanic. They can use specialized tools and equipment to diagnose and repair the issue.
