Bendix’s range of Electronic Brake Wear Sensors are designed to be a direct OE replacement and cover over 900 applications.
Electronic Brake Wear Sensors are mounted on the brake pad on any combination of the four wheels, and may have sensors on 1 to 4 corners of the vehicle. When the brake pad wears and the Electronic Brake wear sensor makes contact with the rotor, a warning is given, usually in the form of a light on the vehicles dashboard.
Wear sensors are designed to break or complete a circuit as the brake pad wears, and hence are not re-useable and need to be changed whenever the brake pads are replaced or the warning light indicates.
What does a Brake Pad Wear Sensor do?
The Brake Pad Wear sensor, or brake wear indicator, is an added safety feature on many vehicles used to warn a vehicle’s driver if their brake pad’s life becomes too low.
Where are these sensors located?
The Brake Pad Wear sensor is mounted on the brake pad and routed through the caliper in any combination of the four wheels. Vehicles have sensors on one to four wheels.
What are the common causes of failure?
Brake Pad Wear sensors are designed to “fail” as brake pads wear. They should be changed whenever the pads are replaced or when the vehicle’s warning light indicates.
How to determine when to change your brake pad sensors:
-
Electronic Brake Wear Sensors should be changed whenever the pads are replaced
- If they have made contact with the rotor they cannot be reused
- Even if they have not made contact they should still be replaced with every pad change
- Materials become worn during their service life and can affect their functionality
- To ensure sensor performance throughout the life of the new pads they should be replaced with a new sensor
