Common Reasons for the Brake Warning Light
Several reasons can trigger the brake warning light in your E60. These range from low brake fluid to worn brake pads and even issues with the ABS system. Identifying the root cause is the first step to resolving the issue and ensuring your vehicle’s safety.
Low Brake Fluid
One of the most common culprits is low brake fluid. Over time, brake fluid levels can decrease due to wear and tear. Check your brake fluid reservoir and top it off if necessary.
Worn Brake Pads
Worn brake pads are another frequent cause. As your brake pads wear down, a sensor triggers the warning light. If your pads are worn, it’s crucial to replace them immediately.
Faulty Brake Sensor
Sometimes, the brake sensor itself can malfunction. This can lead to a false warning light even if your brake pads and fluid levels are fine.
ABS Issues
Problems with the Anti-lock Braking System (ABS) can also trigger the warning light. This requires a more advanced diagnostic approach.
