What Causes a Brake Light to Come On?
There are several reasons why your brake light might be illuminated. Here are some of the most common causes:
- A faulty brake light switch: This is one of the most common causes of a brake light coming on. The brake light switch is responsible for sending an electrical signal to the dashboard when the brake pedal is pressed. If the switch is faulty, it can cause the brake light to stay on even when the brake pedal is released.
- A worn-out brake pad: Worn-out brake pads can cause the brake light to come on because the brake sensor is detecting that the brake pads are not making proper contact with the brake rotor.
- A loose or corroded brake wire: A loose or corroded brake wire can prevent the brake light from functioning properly, causing it to stay on even when the brake pedal is released.
- A problem with the brake light bulb: A faulty brake light bulb can cause the brake light to stay on even when the brake pedal is released.
- A problem with the brake fluid level: Low brake fluid levels can cause the brake light to come on because the brake sensor is detecting that the brake fluid is not at the correct level.
- A problem with the brake master cylinder: A faulty brake master cylinder can cause the brake light to come on because it’s not able to send the proper signal to the dashboard.
