Service Overview

Brake pad wear sensors are electronic devices that monitor the thickness of your brake pads and alert you when they need replacement. When the brake pads wear down to a certain point, the sensor makes contact with the brake disc, completing an electrical circuit that triggers a warning light on your dashboard.

These sensors are designed to be replaced along with the brake pads. At Car Services in Reading, we replace your brake pad sensors whenever we perform a brake pad replacement to ensure your warning system continues to function correctly and keeps you informed about your brake condition.

Frequently Asked Questions

A brake pad wear sensor is a small electronic device mounted on the brake pad. It has a wire that runs at a certain depth in the pad material. When the pad wears down to that level, the wire makes contact with the brake disc, triggering a warning light on your dashboard.

Yes, brake pad sensors are designed to be replaced every time you replace your brake pads. Once the sensor has triggered the warning light, it cannot be reset and must be replaced with a new one to continue monitoring your brake pad wear.

While you can drive with the warning light on, it's not recommended to do so for long. The warning indicates your brake pads are worn and need replacement soon. Continuing to drive could damage your brake discs and compromise your safety.

There are two main types: contact sensors (which trigger when they touch the disc) and wear sensors (which measure pad thickness electronically). Some modern vehicles also have continuous wear sensors that provide real-time pad thickness data to the vehicle's computer.
