Brake Pad Wear Sensor, Aftermarket - Rear - E46 M3

Brake Wear Sensors are key safety components that allow worry-free driving without the need for constant visual inspection of your brake pad material. Once the brake lining dash light is illuminated on your dash, this is a warning of thin brake pad material. Pads should be replaced as soon as possible, and the sensor is a required replacement once the brake lining dash has come on.

• Precise factory fitment
• Worry-free driving until dash light illuminates
• One sensor required per axle 

Priced per REAR brake wear sensor. Only one is needed for this application, and on the E46 M3 the rear brake pad sensor wire installs on the right rear (passenger rear, on US / left hand drive models). 

TECH NOTE: On a majority of applications the brake lining light can be reset easily by installing a new sensor and turning the ignition to the second position (without starting the car) for approximately one minute - or until the light goes out. Refer to your Bentley service manual for further instruction if this method doesn't work.
