ABS 39724 Wear Indicator
The ABS 39724 Wear Indicator is a precision-engineered sensor designed to monitor the wear of brake pads on disc‑brake vehicles. It provides an early warning system that alerts drivers when pad thickness falls below safe operating limits, thereby enhancing safety and preventing costly damage to rotors.
Key Features
- High‑Accuracy Contact: The sensor’s contact element is calibrated to detect pad wear at the critical threshold of approximately 93 mm in length, ensuring reliable operation across a wide range of brake pad materials.
- Universal Compatibility: Engineered for use on front and rear axles—left and right—this indicator fits seamlessly into the brake systems of numerous luxury and performance vehicles, including MERCEDES‑Benz, INFINITI, and a broad spectrum of models such as C‑class, E‑class, G‑class, Q30, CLA, CLS, EQC, GLB, GLC, GLE, GLS, and many others.
- Robust Construction: Built with high‑grade materials that resist corrosion and wear, the sensor maintains functionality even under harsh operating conditions and extended service intervals.
- Simple Installation: The indicator is designed to replace existing contact sensors without requiring extensive modifications. It aligns with OEM specifications (e.g., part numbers 410685DN0A, 1695401617, A1695401617) for a plug‑and‑play experience.
- Clear Warning Signal: When pad wear reaches the critical limit, the sensor activates an electrical circuit that triggers the vehicle’s dashboard warning light or audible alert, providing immediate feedback to the driver.

Installation Overview
- Remove Existing Sensor: Detach the current wear indicator by loosening mounting screws and disconnecting the electrical connector.
- Align New Indicator: Position the ABS 39724 sensor so that its contact surface aligns with the brake pad’s wear line. Use the provided alignment marks to ensure precise placement.
- Screw Securely: Tighten mounting screws to the specified torque (typically 15–20 Nm) to guarantee a firm fit without over‑tightening.
- Reconnect Wiring: Attach the electrical connector, ensuring a secure and correct polarity connection.
- Test Functionality: After installation, activate the vehicle’s brake system to confirm that the warning light or alert engages when pad wear reaches the threshold.
Maintenance Tips
- Inspect the contact surface periodically for signs of corrosion or debris. Clean gently with a soft brush and mild solvent if necessary.
- Avoid excessive vibration by ensuring mounting bolts are tightened to specification during every service interval.
- Replace the sensor immediately if the warning system fails to activate under normal conditions, as this may indicate internal failure or misalignment.
Benefits for Drivers
The ABS 39724 Wear Indicator delivers several critical advantages:
- Enhanced Safety: Early detection of pad wear prevents sudden loss of braking performance and protects rotors from damage.
- Cost Savings: By alerting drivers before pads reach the end of life, the sensor reduces the frequency of costly brake replacements.
- Peace of Mind: Knowing that the vehicle’s braking system is actively monitored allows drivers to focus on the road without worrying about hidden wear issues.
Conclusion
The ABS 39724 Wear Indicator is a reliable, high‑performance component essential for maintaining optimal brake function in modern disc‑brake vehicles. Its precise contact length of 93 mm, universal fit across major luxury brands, and straightforward installation make it an indispensable tool for both professional mechanics and informed vehicle owners seeking to uphold safety standards.
