Brake handle not fully lowered
One of the reasons your parking brake light remains on could be due to a defective brake handle that doesn’t fully lower due to certain issues.
Problems regarding brake handle issues such as contaminated or reduced fluid levels, worn out brake pads, a faulty master cylinder or possibly even due to a defective switch are the reason why it cannot be fully lowered.
Parking brake not disengaging
In some cases, the parking brake light stays on when the parking brake is not releasing as it should. This may be caused by misaligned shoe positioning, rusting or sticking cables connected to the lever and brakes/pads. It’s like your car’s way of saying, “Hey, something’s not right here!” Misaligned shoe positioning can happen over time due to regular wear and tear or during a brake service if the shoes are not properly aligned.
Rusting or sticking cables can be due to harsh weather conditions or lack of maintenance. These cables connect the lever to the brakes/pads and are crucial for the correct operation of the parking brake. If these cables are rusted or stick, they can prevent the parking brake from releasing properly, causing the light to stay on.
Low brake fluid level
The parking brake light may stay on if there’s not enough brake fluid or if the pressure in the brake system is low. This can happen if there’s a leak or a problem with part of the brake system. It’s important to check the brake fluid often and fill it up if needed. If you’re constantly having to add more brake fluid, you should have a mechanic check your vehicle for any problems.
Bad brake fluid level sensor
A bad brake fluid level sensor is another common reason why your parking brake light stays on. When the sensor malfunctions or fails, it may incorrectly signal that the brake fluid level is low, causing the parking brake light to stay on on your dashboard.
A malfunctioning brake fluid sensor can be due to various factors. Age and wear and tear can degrade the sensor over time. Exposure to extreme temperatures can damage the sensor. Contamination from dirt or debris in the brake fluid can interfere with the sensor’s ability to accurately detect the fluid level. Additionally, damage to the sensor from an accident or rough handling during maintenance can cause it to malfunction. Careful handling of these components is crucial to prevent damage.
Faulty wiring or electrical issues
Poor wiring or a broken connection in the circuit might be what’s causing your parking brake light not to turn off. To identify issues with your vehicle’s braking system, utilize a multimeter and look for any variations of voltage levels in its components. Disconnecting and joining together the wires that link up at the switch will indicate if they are functioning correctly – as this should cause them to illuminate when successful.
Malfunction in the anti-lock brake system
The parking brake light and anti-lock brake system may keep their light on constantly if there is an issue in the braking system. If these lights appear, it’s a sign of a malfunction occurring within the brakes.
Indicators such as an unresponsive pedal, warning lights lighting up or erratic behavior can also point to an Anti-Lock Braking System problem. Expert help should be sought out right away for resolution purposes.
Can I Fix Parking Brake Light Issue By Myself?
Yes, you can resolve some problems related to the parking brake light on your own, particularly those that involve simple tasks such as addressing low brake fluid levels. But, when it comes to a malfunctioning parking brake, which is generally a sign of more complex issues, it’s recommended to seek help from a professional for accurate diagnosis and repair.
Is it safe to drive with the parking brake light on?
It is generally not safe to drive with the parking brake light on. Driving with the parking brake light on can cause a lot of problems. It can make your brakes work less effectively, create too much heat, wear out the brake parts unevenly, damage the parking brake system, and even put you in danger during emergencies.
