Car’s Brake Light Keep Turning On? Here are Tips to Fix it!

Having your car brake light on all the time is not only annoying, but it can also be a sign of a serious problem with your vehicle’s brake system. As one of the critical components in a car’s safety system, a properly functioning brake light is essential for signaling to other drivers when you are slowing down or stopping. If the brake light stays on even when the brake pedal is not pressed, it could signal some technical issues that require immediate attention. This article TransTRACK will discuss the common causes of this problem and the steps you can take to fix it, so you can drive safely and calmly.

Causes of the Car Brake Light Staying On

The car brake light stays on all the time can be caused by the following factors:

Damage to the Brake Switch

A damaged or malfunctioning brake switch may cause the brake light to remain on. This switch is responsible for detecting when the brake pedal is pressed, and if this switch is damaged, the signal informing you that the brakes have been released may not be sent.

Problems with the ABS System

Problems with the Anti-lock Braking System (ABS) system can affect the function of the brake lights. If the ABS system is damaged or malfunctions, it may cause the brake light to stay on as a warning sign that there is a problem with the brake system.

Brake Switch Retaining Rubber Loose

The brake switch retaining rubber serves to keep the switch in the correct position. If this rubber is loose or damaged, the switch may remain in a position that causes the brake light to illuminate continuously.

Brake Stand Has a Problem

If the brake mount or any other mechanical part associated with the brake pedal has a problem or is damaged, this can cause the brake switch to remain in the active position, which then causes the brake light to stay on.

Brake Fluid Running Out

A lack of brake fluid in the system can cause the sensor to detect abnormal brake pressure, which can then trigger the brake light to stay on as a warning that the brake system needs to be checked.

If your car’s brake light is always on, it is advisable to have the car checked by the nearest repair shop to get a proper diagnosis and appropriate treatment.

How to Fix a Car Brake Light that Keeps Turning On

Overcoming a car brake light that stays on can be done with the following steps:

Resetting the Brake Switch Mount

First, identify the location of the brake switch which is usually located above the brake pedal, close to the pedal shaft. Check the physical condition of the switch and its mounting to see if there is any looseness or damage. Then, loosen the nuts or bolts that hold the brake switch in place. Slide the switch a little at a time while checking that the brake light goes out when the pedal is not pressed and comes on when the pedal is pressed. After finding the right position, retighten the nuts or bolts to secure the switch in place. Test the brake pedal several times to ensure that the brake light only comes on when the pedal is depressed.

Replacing the Brake Switch

Prepare the necessary tools and materials, such as a new brake switch according to your car’s specifications, as well as tools such as a wrench or screwdriver. Disconnect the electrical connector connected to the old brake switch, then remove the nut or bolt that holds the brake switch in place. Make sure the new brake switch is the same size and connector as the old one. Install the new brake switch in place and tighten the nuts or bolts. Reconnect the electrical connector and start the engine to test the brake pedal function, ensuring the brake light is working properly.

Replacing the Retaining Rubber

Check the retaining rubber between the brake pedal and the brake switch, which acts as a cushion for the switch when the pedal is not depressed. If the retaining rubber looks worn, cracked, or missing, this could be the cause of the brake light coming on constantly. Carefully remove the old retaining rubber, some retaining rubbers are only installed by clicking or tucking. Fit the new retaining rubber in place and ensure that it fits snugly and does not come off easily. Once the retaining rubber is in place, test the brake pedal function to ensure that the brake light is functioning normally.

With these steps, you can solve the problem of an always-on brake light and ensure that your car’s brake system is functioning properly and safely.

Troubleshooting an always-on brake light requires a good understanding of the brake system and its components. By following the steps of readjusting the brake switch mounts, replacing damaged brake switches, and ensuring the retaining rubber is in good condition, you can keep your car’s brake system functioning optimally. However, if you are unsure or need further assistance, it never hurts to consult a professional.
