Rear brake wear sensors are essential components of a vehicle's braking system that help drivers monitor the condition of their brake pads. These sensors are typically made of a conductive material that wears down as the brake pad wears out, creating a signal that is sent to the vehicle's onboard computer. When the computer detects that the brake pads are worn out, it will alert the driver with a warning light or message. Rear brake wear sensors are important safety features that help drivers stay aware of their vehicle's braking performance and ensure that their brakes are in good working condition.

Frequently Asked Questions (FAQs)

1. Do rear brakes have sensors?

Most basic brake pad wear systems have a sensor in the front and rear of one corner of the vehicle. The sensors are mounted on the inboard brake pad because it typically wears the fastest. On higher-end systems the number of sensors increase to every inboard brake pad.

2. Do you have to replace brake pad wear sensors?

As brake pad wear sensors are designed to break, they should be replaced as a matter of course every time new brake pads are fitted. It's also advisable to regularly inspect the sensors, in between pad changes, and replace where necessary.

3. What does the rear brake sensor do?

This is used to gather information such as wheel speed, brake pressure, brake disc temperature, brake operating time and mileage to estimate the life left in your brake pads.

4. Where is the brake wear sensor?

The brake pad wear sensor accurately informs the driver about the current wear of the vehicle's brake pad. Mounted in the brake pad, one sensor for the front axle and one sensor for the rear can be installed to determine and indicate when the driver needs to perform a replacement.
