Common Issues It Can Help Address

• Brake wear warning light remains on after pad replacement
• Inaccurate pad wear monitoring from a damaged rear sensor
• Electrical signal loss caused by heat or wear at the sensor lead
• Need for an OE-style rear brake wear sensor on select BMW models
• Brake service completion when the original sensor is worn or broken

Installation Notes and Tips

Replace the rear wear sensor during brake pad service whenever the original sensor is worn, damaged, or triggered. Verify connector shape, terminal style, and harness routing before installation. Confirm vehicle-specific rear fitment for your BMW 740i, 750i, 760Li, or ActiveHybrid 7 application before ordering.
