Common Causes of a Brake Warning Light
The most frequent reason for the brake warning light on Mercedes Sprinter is worn brake pads. These pads are designed to wear down over time, and the warning light serves as a crucial reminder to replace them. However, low brake fluid levels can also trigger the warning light. The brake system is hydraulic, relying on fluid pressure to function correctly. A leak or insufficient fluid can compromise braking performance.
Another common culprit is a faulty brake light switch. This switch activates the brake lights when the pedal is depressed, and a malfunction can cause the warning light to illuminate. Lastly, a problem with the ABS (Anti-lock Braking System) can also trigger the warning light. The ABS helps prevent wheel lockup during hard braking, enhancing control. Any issues within this system necessitate prompt attention.
