What It Helps Address

• Brake wear warning light triggered by a failed sensor
• Damaged or worn front brake pad wear sensor wiring
• Loss of electronic pad wear monitoring after brake service
• Incorrect sensor fitment on Audi Q5 front brake applications
• Intermittent wear-indicator signal caused by heat and age

Installation Notes and Tips

Verify the vehicle’s front brake configuration before ordering, especially Brembo brake equipment and rotor diameter on Audi Q5 applications. Inspect the sensor routing, connector shape, and terminal style against the original part before installation. Replace the sensor when servicing worn pads or when the existing sensor shows damage, since a reused sensor may not provide reliable wear-indicator operation. Confirm the harness length and connector orientation match the original setup on the vehicle.
