Common Causes of the Service Brake Warning

Several factors can trigger the “Service Brake” warning in a 2005 Mercedes Benz E320. Let’s explore the most common culprits:

Brake Pad Wear

One of the most frequent reasons for this warning is worn brake pads. As you drive, your brake pads gradually wear down. When they reach a certain thickness, a sensor triggers the warning light, indicating it’s time for a replacement.

Brake Fluid Level

Low brake fluid is another common cause. Brake fluid is essential for transmitting hydraulic pressure to the brakes, enabling them to function correctly. A leak in the system or simply low fluid due to wear can activate the warning.

Brake Sensor Malfunction

Sometimes, the brake pad wear sensors themselves can malfunction. A faulty sensor might trigger the warning light even if the brake pads are still in good condition.

ABS Issues

The Anti-lock Braking System (ABS) is a crucial safety feature. Problems within the ABS module, wheel speed sensors, or related components can trigger the “Service Brake” warning.
