Structure and inner electrical connection
2-stage brake pad wear sensor: The brake pad wear sensor operates in 2 stages. A resistor is additionally integrated in the 2nd stage. The DSC detects the 2nd stage via the changed voltage measurement.
1-stage brake pad wear sensor: When the conductor path is worn through, approx. 5 % of the remaining brake pad thickness is reached.
