When the brake warning light illuminates on the dashboard, you must rectify the problem immediately. It may be a serious problem with deadly consequences if left unchecked. You may be wondering why the yellow brake light is on and how to reset it.
Worn brake pads, low brake fluid, and an engaged emergency brake may cause the yellow brake light on BMW Driving with yellow light is dangerous. You must have a mechanic diagnose the problem and undertake the necessary solutions.
The yellow lights on your BMW may come on without warning. The first thing to think about is taking off the wheel and checking. If the pads are okay, you can try resetting the brake light. If the brake lights remain even after resetting, you must know what to do in such a situation.
What Is The Yellow Brake Light On BMW?
Rectifying the problem requires discovering the underlying factor that caused the problem.
Worn Brake Pads
Placing your foot on the brake pedal makes the brake pads press on the brake rotors or drums connected to the spinning wheels. It produces friction forcing the wheels to slow down, making your car stop.
Regular friction gradually wears away the brake pads. Wherever you use the brake pedal, you contribute to wearing away the brake pads. Over time, the brake light starts acting up to let you know that the pads need replacement.
Brake Fluid Is Low Or Leaks
Brake fluid transfers the force of the foot on the brake pedal to the wheel and brake pedal. Leaking brake fluid will make your Beemer stop braking completely.
When low on brake fluid, the capability declines. Low brake fluid wears out the brake pads since worn-out pads need more brake fluid for the required force to make your car brake.
Engaged Emergency Brake
The emergency brake light is the car’s warning light since the car is running and the emergency brake is engaged. The warning light lets you know when there’s something wrong by illuminating the brake light.
ABS Problem
The Anti Braking System (ABS) prevents you from locking up or applying too much pressure to your brakes. Your car will start skidding when the wheels stop turning, but the car is going too fast. It causes a loss in total control of the vehicle, which is very dangerous during high-speed driving.
The ABS light may come on because of various problems, including:
- A malfunctioning ABS module
- Low level in the fluid reservoir
- Broken wheel speed sensor
- The system is turned off.
How Do You Reset It?
You’ll have to consult your trusted mechanic to determine the source of the problem. Afterward, the mechanic will give you a comprehensive report, including the scope and cost of the appropriate repairs.
The engine has various lights, and the mechanic will determine which light is on and inspect the whole brake system while checking the brake pads and fluid level. A brake warning light indicates a serious problem.
After checking your brake system, ensure that your emergency brakes are off, and don’t put the car on the road. A low brake fluid level may make the brakes stop functioning.
