What This Product Does

The sensor forms part of the vehicle's pad-wear warning circuit, helping indicate when brake pads require renewal. It is a monitoring component rather than a replacement for the pads or discs.

Functions

• Detects pad wear at the sensor position.
• Provides an input to the brake-wear warning system.
• Supports brake servicing and maintenance checks.
  
  

Technical Details

• Installation position: Front.
• Brand: OE Match.
• Specified brake option codes: 1ZI, 1ZU, 1ZV and 1ZW.
  
  

Symptoms of Fault

• A pad-wear warning remains after new pads have been fitted.
• Visible damage to the sensor cable.
• Broken retaining clips or an insecure sensor connection.
  
  

Why Replacement Matters

Sensor renewal normally accompanies pad replacement and may also be needed where wiring or the sensing element is damaged. A warning alone does not establish which component has failed; inspect pad condition, connections and cable routing before replacing parts.

FAQs

Is the model year enough to confirm compatibility?
No. Match the part reference and front brake option code as well as the vehicle details.

Should the sensor be renewed during a pad change?
Renewal is normally recommended alongside new pads, particularly if the existing sensor has worn or sustained damage.

Does this sensor replace worn braking components?
No. Pads, discs and associated hardware require separate inspection; changing the sensor does not correct their wear.
