How does the brake wear sensor work on a Mini Cooper?
When the Brake Wear Service indicator illuminates, one of the two Brake Wear Warning Sensors has been triggered. The brake wear sensor is a wire loop that gets worn down against the rotor. Once the wire is worn thru and the circuit is opened, the brake wear indicator is illuminated.
Where is the sensor on the front brake pad?
Typically two. One sensor is located on one front brake pad (left front). The second wear sensor is on the right rear brake pads. What is BMW brake pad sensor resistance?
How do you replace a brake sensor on a BMW?
If replacing the front brake pad sensor, jack up the driver’s side wheel. If replacing rear brake pad sensor, jack up passenger side wheel. Remove the wheel from the vehicle. Locate the brake pad wear sensor on the brake pad. Use a flat head screwdriver to pry out the old sensor. Unhook the sensor from the brake caliper release valve.
When do I need to change the brake sensor?
The wear sensors are designed to break or complete a circuit once the brake pad has worn enough for the sensor to contact the brake rotor. A warning light will usually light up on the dash, indicating it’s time for a brake pad change.

How does the brake wear sensor work on a BMW?
This guide focuses only on the brake wear sensor and assumes you have already replaced the brake pads. BMW brake wear sensor is nothing more than a wire that runs at the tip of the sensor. 12-volt typically feeds the sensor at all times. Once the brake pads wear out, the sensor’s tip where the wire runs are cut as well, which opens the circuit.
How does the brake wear indicator work on a car?
The embedded sensor in the brake pad 2 contacts the rotor and creates a connection to ground of the sensor. The metal plate 3 contacts the rotor and creates a noise. This wear clip should be positioned so that the rotor contacts the clip before it contacts the brake pad.
