Decoding the Brake Pad Warning Light
The brake pad warning light is triggered by a sensor embedded within the brake pad assembly. This sensor monitors the thickness of the brake pad material. When the brake pad material wears down to a predetermined level, the sensor activates the warning light on your dashboard. This usually indicates that it’s time to replace your brake pads. However, there can be other reasons for the light to come on, such as a faulty sensor or wiring issue.
The location of the brake pad wear sensor can vary depending on the specific model and year of your Mercedes A Class. Typically, it’s located within the brake pad itself, close to the backing plate. As the brake pad wears down, the sensor eventually makes contact with the brake rotor, completing a circuit and triggering the warning light.

A faulty sensor can trigger the warning light even if the brake pads are still in good condition. A visual inspection of the sensor and its wiring is recommended. Look for any signs of damage, corrosion, or loose connections. If the sensor is damaged or the wiring is compromised, it will need to be replaced.
