What is the reason why the brake fault light comes on? What should I do when the brake fault light comes on? When the brake fault light turns on ?…., which components should you inspect?
It can be irritating to have a warning light on the instrument cluster. These fault lights are very important and can lead to severe consequences. A brake fault lamp is a warning sign that your vehicle’s braking system is not working properly. This is a safety feature. You should not drive while the light is on. Instead, take your vehicle to a workshop to have the problem diagnosed immediately.
What do you do if the Brake Malfunction Light is On?
Handbrake & Parking Brake Should Be Checked
Once the ignition has been turned on, the lights on your instrument panel will turn on for a short time before going out. This is to ensure that all warning lights work properly. If all the lights on the vehicle are turned off, but the brake fault light remains lit, it’s best to not drive the vehicle until the problem is resolved. You should first make sure the parking brake (or hand) is not disabled. Some vehicles use the same warning lamp, even though there are many different models. The brake pads will be damaged if the parking brake is engaged. The parking brake should be completely disabled if the light comes on continuously.
Keep calm when the brake malfunction light is illuminated while driving. The first thing you should do is to drive the car to a safe location and then stop by slowing down to apply the brakes. It is safe and sensible to call a tow truck in order to transport the vehicle to the mechanic.
It is important to check brake fluid
Next, you need to check the fluid level. Low fluid levels will usually cause the brake malfunction lamp to go on. Low brake fluid levels indicate a leaky system. This can cause brakes to cancel completely, which is a serious problem.
You should not ignore brake hydraulic system leakages and take your vehicle to the mechanic immediately.
ABS System Must be Checked
If the fault persists, it could be the ABS (Anti-Lock Braking Systems). It varies depending on vehicle make and model, but many vehicles use the brake fault lamps to indicate an ABS problem. An ABS warning light is also available for new vehicles.
You can only find out if your ABS is causing the ABS problem by taking the vehicle to the garage and having it checked. This light can come on for a variety of reasons, including an electrical fault or a dirty wheel speed sensor. The ABS system won’t work properly if the speed sensor is damaged. ECU fault codes should always be read using the diagnostic device. The vehicle should be repaired accordingly.
These three issues are most likely to cause the brake fault lamp to turn on. The sensors that measure brake fluid and the parking brake sensor in the brake mastercylinder may not be working properly. The cables could also be faulty. A problem with the cables can also cause the brake light not to turn on.
Important Note: The brake fault lamp will turn on on some instruments panels if the brake lamps in the taillights are damaged or blown. The malfunction light will turn off when the brake bulbs have been replaced.
