What It Is Used For

• Restoring brake pad wear warning function
• Replacing a damaged or worn sensor lead
• Addressing warning light issues tied to pad wear monitoring
• Maintaining electrical continuity in the brake wear circuit
• Supporting proper brake service on covered BMW rear applications

Installation Notes and Tips

Verify connector shape, terminal count, and harness length against the removed sensor before installation. Route the lead to avoid contact with moving suspension or brake components, and confirm the sensor is seated securely in the brake pad wear circuit. Fitment is listed for rear positions only on the specified BMW models and years.
