Installation & Maintenance Guidelines

Installing the TRW Brake Pad Wear Indicator Sensor is a straightforward process that can be completed by experienced mechanics or knowledgeable DIY enthusiasts. Follow these steps for optimal performance:

1. Remove Existing Brake Pads: Safely lift the vehicle and remove the wheel to access the brake assembly.
2. Position the Sensor: Align the sensor’s contact arm with the designated slot in the brake pad stack. Ensure it is seated firmly but not over‑tightened.
3. Secure Mounting: Fasten the sensor housing using the provided mounting screws, ensuring a snug fit that resists vibration.
4. Connect Electrical Lead: Attach the sensor’s wire to the vehicle’s brake warning circuit or dedicated indicator module. Verify correct polarity and secure connections with heat‑shrink tubing.
5. Reinstall Brake Pads & Wheel: Place new pads, reassemble calipers, and reinstall the wheel. Torque all fasteners to manufacturer specifications.
6. Test Functionality: Activate the brake system and observe the indicator light or dashboard message. The sensor should trigger when pads reach the wear threshold.

Regular inspection of the sensor’s contacts and housing is recommended during routine brake maintenance. Replace any worn components promptly to maintain reliable warning functionality.
