Genuine-fit A.B.S. 39677 warning contact — restores accurate pad wear warnings. Ships nationwide, order now for fast delivery.
An illuminated brake wear warning light with plenty of pad material remaining, or no warning at all as pads wear thin, usually means the sensor itself has failed. The A.B.S. 39677 warning contact replaces a faulty sensor with an OE-matched part.

Use Cases and Applications
This warning contact is suited for addressing a stuck or malfunctioning brake wear warning light, replacing a sensor during pad service, and restoring accurate pad wear monitoring. Typical scenarios where drivers choose this part include:
- Replacing a sensor after the wear warning light stays on despite adequate remaining pad material.
- Restoring warning functionality after a sensor fails to alert at the expected wear point.
- Installing a new sensor alongside a brake pad replacement, as many manufacturers recommend.
- Addressing a sensor damaged during a previous brake service.
Because wear sensors are manufactured for a specific electrical connector and mounting configuration, this part is intended as a direct match for the applications it’s designed for — always confirm fitment against your vehicle’s OE part number before ordering. Keeping this sensor in good working order helps protect your rotors from the accelerated wear and damage that comes from driving on pads that are worn past their service life.

Can I install this sensor myself?
Experienced DIY mechanics can typically install a wear sensor at home, especially during a brake pad replacement when the wheel is already off. If you’re not comfortable working on your brake system, we recommend having it installed by a qualified technician.
Why does my brake wear warning light stay on even with new pads?
