Reset Parking Brake Light

We’ll walk you through the process of resetting your parking brake light in this post, along with some advice on how to keep yourself and your car safe.

How Do You Reset Your Parking Brake Light?

To reset your parking brake light, you have to check and fix a few things such as the parking brake, brake fluid level, brake pads, electronic parking brake system, parking brake switch, brake fluid leaks, anti-lock brake system, and finally reset the parking brake light manually.

1. Check the Parking Brake

To stop the warning light from coming on, it is crucial to make sure the parking brake engaged fully. The vehicle’s center console, which is situated between the front seats, is where you’ll normally find the parking brake, sometimes referred to as the handbrake or emergency brake. Pull the lever up to test the parking brake.

The parking brake light could come on if the brake is not fully applied. Be careful and make sure to fully extend the lever until the brake engages or you hear a click. A defective sensor or switch might be to blame if the parking brake lever is fully engaged and the parking brake warning light is still on.

Before checking the other parts of the parking brake system, it is crucial to make sure the parking brake is fully engaged. If you need instructions on how to apply the parking brake, see the owner’s handbook for your car.

There are certain cars that feature an electronic parking brake that you activate by pressing a button or switch rather than pulling a lever. In these situations, make sure the parking brake is fully engaged by depressing the button or switch until a warning appears on the dashboard.

2. Check the Brake Fluid Level

If the brake fluid level is low, the warning light can come on, signaling a problem with the braking system. In order to transfer power from the brake pedal to the brake pads or shoes, brake fluid is an essential part of the car’s brake system. Therefore, it’s crucial to check that there is enough brake fluid in the system to prevent brake failure.

 

Find the brake fluid reservoir beneath the hood of your car and check the amount of the brake fluid there. The reservoir is usually marked with a brake sign and is situated on the driver’s side of the engine compartment.

By examining the marks on the side of the reservoir, you may determine the brake fluid level. The fluid level should be between the minimum and maximum markers. If the fluid level is below the minimal level, either the brake pads are worn out or there is a leak in the braking system.

Use the brake fluid advised for your vehicle to top off the brake fluid level if it is low. Don’t overfill the reservoir because this might lead to braking fluid spilling out and harming other engine parts.

3. Check the Brake Pads

The parking brake light may come on as a result of worn brake pads, signaling that it’s time to repair the brakes. The braking system’s most important component, the brake pads, applies friction to the brake rotor or drum to assist in stopping the car.

Worn Brake Pads

To avoid brake failure, it is crucial to make sure the car’s brake pads are in good condition. Remove the wheel to inspect the brake pads for damage and wear. The brake pads must be changed if they are less than 3 millimeters thick.

Additionally, look for evidence of wear on the brake rotor or drum, such as grooves, fractures, or warping. The brake pads may wear out fast or the car may vibrate as a result of worn rotors or drums. To achieve equal braking, it is advised to change all four brake pads at once if they need to be replaced.

Use the brake pads that are advised for your car, then install them in accordance with the manufacturer’s directions. Test the brakes by slowing down and lightly pressing the brakes after replacing the brake pads. There can be an issue with the braking system that needs to be fixed if the brakes feel mushy or do not react as expected.

4. Check the Electronic Parking Brake System

The majority of contemporary cars come with electronic parking brakes, which work differently from conventional mechanical ones by activating the parking brake via motors and wires. The parking brake light turns on if there is a possible problem with the electronic parking brake system.

Start by making sure the parking brake is completely disengaged before inspecting the electronic parking brake system. The owner’s handbook should be consulted for detailed instructions on how to inspect the electric parking brake system.

The electronic parking brake system fault codes can be checked in some vehicles’ diagnostic modes. Visual inspection of the electronic parking brake system is another method of verification.

Look for frayed or faulty brake calipers, frayed or damaged cables and wires, and worn brake pads. Also, look for wear or damage on the electronic parking brake switch. It could be necessary to repair the electronic parking brake switch if it is broken.

5. Check the Parking Brake Switch

When the car’s parking brake is applied, the parking brake switch is in charge of communicating with the car’s computer to activate the parking brake light. Start by finding the switch below the parking brake lever or pedal in order to inspect it. While some cars have a separate parking brake switch, others have one built into the brake pedal position sensor.

For exact directions on where to find the parking brake switch, consult the owner’s handbook. Once you’ve found the switch, look for any obvious wear or damage. The parking brake light may continue to be on if the parking brake switch is broken or worn and is unable to communicate with the car’s computer.

Test the switch’s continuity with a multimeter. If there is no continuity, the switch can be broken and has to be replaced. The replacement of the parking brake switch can be straightforward, but it can need some technical expertise and specialized equipment.

6. Check for Brake Fluid Leaks

The parking brake light may illuminate due to insufficient brake fluid, which might be a sign of a braking system leak. Any component of the braking system, such as the brake lines, calipers, wheel cylinders, and master cylinder, might experience a brake fluid leak. Start by looking for any leakage in the brake lines and connectors before checking for brake fluid leaks.

Checking Brake Fluid Leaks

Examine the area surrounding the wheels, brake lines, and master cylinder for any damp patches or puddles of brake fluid. The afflicted component has to be fixed or replaced if any leaks are discovered. Leaks in the brake fluid can have major negative effects on safety and need to be fixed right away.

If no leaks are discovered, look for any leaks in the master cylinder. The parking brake light may come on if the brake fluid level drops as a result of a malfunctioning master cylinder. Examine the master cylinder for evidence of rust or other damage.

The master cylinder has to be fixed or replaced if any problems are discovered. In rare circumstances, a bad brake booster might also activate the parking brake light. Engine vacuum is used by a brake booster to help in stopping.

7. Check the Anti-lock Brake System

The ABS was created in order to avoid skidding caused by the wheels locking up during strong braking. The parking brake light could come on if the ABS isn’t working properly. Start by looking at the ABS sensors at each wheel to test the ABS. Keep an eye out for any damage or wear, such as cracks or frayed wires.

The ABS brake sensor must be changed if any problems are discovered. Next, look for any problems or error codes in the ABS controller. A computer called the ABS controller keeps track of the ABS and can spot any problems. To diagnose the problem and read any error codes, use a diagnostic scanner.

If there are no problems with the sensors or controller, the ABS pump or modulator may be at fault. The hydraulic pressure required for the ABS to operate properly is produced by the ABS pump. The parking brake light could come on if the pump is malfunctioning. The modulator controls the pressure in the ABS and, if it isn’t functioning properly, may also activate the parking brake light.

8. Reset the Parking Brake Light Manually

Depending on the make and model of your car, there may be a difference in the procedure for resetting the light. The ignition key must be turned to the “on” position in order to reset the parking brake light, but the engine must not be started first. The parking brake release button should then be depressed and held.

Parking Brake Button

Typically, this button is found on the parking brake pedal or lever. Pull the parking brake lever or pedal up to the fully engaged position while continuing to hold the release button. Hold the release button down while maintaining the parking brake engagement for around 10 seconds. Press the release button once more after releasing the parking brake.

After that, turn off the engine and wait a short while. Then, check to see whether the parking brake light has been reset after turning the ignition key back on. To reset the light, you might occasionally need to utilize a diagnostic tool.

Conclusion

To protect your safety and the correct operation of your car, it’s imperative to deal with the problems that are causing the parking brake light to come on as soon as possible.

To sum it up, the main ideas we’ve discussed are:

  • To identify the problem, check the anti-lock brake system, brake fluid level, brake pads, electronic parking brake system, etc.
  • The parking brake light should automatically switch off once the issue is fixed and if not, a manual reset of the light is possible.
  • Turn on the engine, hold down the parking brake button while the light flashes, and then release the button to manually reset the parking brake light.
