Brake Pad Wear Sensors/Indicators From $9.99

Choosing A Brake Pad Wear Sensor

A brake pad wear sensor must suit the brake position and electrical connection on the vehicle. Available parts include individual sensors and sets for selected front, rear or front-and-rear applications. Compare the sensor mounting end, connector and lead routing with the assembly being serviced.

A-Premium offers different package quantities and connector designs. A front sensor is not automatically interchangeable with a rear sensor, even when both are described as brake wear indicators.

How A Brake Pad Wear Sensor Works

An electronic wear sensor is associated with a brake pad and connects to the vehicle's warning circuit. As the pad wears to the point used by that system, the sensor can trigger a warning for brake inspection. Circuit designs differ, so the way a signal is generated is not identical on every vehicle.

Sensor placement is specific to the brake design, and an indicator does not replace physical inspection of the friction material.

Brake Wear Warnings And Inspection

A wear warning calls for checking the brake pads and the indicator system. Pad wear, a damaged sensor lead or a connection problem can each affect the warning on systems designed to detect those faults. Inspect both the friction material and the sensor wiring before deciding which parts are needed.

Follow the vehicle's brake service procedure for the affected axle. The replacement parts can include pads and a sensor, but their contents and service requirements depend on the application.

Frequently Asked Questions (FAQ)

Is a brake wear sensor the same as an ABS sensor?

They report different conditions. A brake pad wear sensor is part of a wear-warning system; an ABS wheel speed sensor monitors wheel rotation for the anti-lock braking system. Their connections and purposes are different, so one does not replace the other.

What is the difference between an electronic sensor and a wear tab?

A mechanical wear tab makes contact with the rotor and produces a warning sound as the pad wears. An electronic sensor sends a signal through a circuit to a warning display. A vehicle may use different wear-warning arrangements depending on its brake design.

Does every wheel have a brake pad wear sensor?

Sensor location and quantity vary with the brake system. Some systems use warning contacts at selected positions rather than a sensor on every pad. Identify the position and quantity specified for the vehicle before choosing a single sensor or a set.

Will the warning clear automatically after the sensor is replaced?

The response depends on the vehicle. Some systems require a brake-service reset after the repair, while a remaining wiring or service issue can prevent a warning from clearing. Complete the required brake work before following the vehicle's reset procedure.

Are wear sensors included with replacement brake pads?

Some brake pad sets include a wear contact, while a sensor may also be sold separately. Check the contents and the requirements for the affected axle so the necessary sensor is available when the pads are serviced.
