2.40585 DT Wear indicator

The Wear Indicator from DT (MPN: 2.40585) is sourced from Sweden and has supplier-listed dimensions of 207 x 42 x 207 mm. It is typically used within the Brakes > Brake Mechanical > Brake Pad Wear Sensor category of automotive replacement parts. Dimensions are provided by the supplier and may include packaging dimensions. Brake pad wear sensors are electronic components integrated with the brake pad assembly, typically located near the friction material. These sensors utilize a physical or electrical method to detect diminishing pad thickness during normal braking operation. Upon reaching a predetermined wear threshold, the sensor activates a warning indicator on the vehicle’s instrument panel. Common technologies include a shear-based pin breaking a circuit or a capacitive measurement of pad distance. Signal transmission is generally resistive, providing a voltage reading to the vehicle’s electronic control unit. Replacement is typically performed alongside brake pad service to ensure continued wear monitoring.
