These OE direct-fit brake wear sensor integrates seamlessly with your Porsche's electronic braking system, ensuring accurate wear monitoring and helping prevent unnecessary brake disc damage caused by excessively worn brake pads.
What Does the Brake Pad Wear Sensor Do?
The brake pad wear sensor is an important safety component that monitors the thickness of the front brake pads. As the friction material wears down, the sensor eventually contacts the brake disc, completing an electrical circuit that activates the brake wear warning light on the dashboard.
Its primary functions include:
- Monitoring front brake pad wear.
- Activating the dashboard brake warning light.
- Preventing excessive brake pad wear.
- Helping protect the brake discs from damage.
- Supporting scheduled brake maintenance.
- Improving overall braking safety.
The sensor provides an early warning, allowing brake pads to be replaced before braking performance is compromised.
Why Do Brake Pad Wear Sensors Fail?
Brake wear sensors are consumable components and are
designed to be replaced during brake servicing. Common reasons for failure
include:
- Normal activation once the brake pads reach their wear limit.
- Heat generated by the braking system.
- Damage during brake pad removal.
- Road debris and moisture.
- Corrosion of the electrical contacts.
- Wiring damage caused by age or movement.
- General wear after years of service.
Once activated, the sensor cannot normally be reused and should always be replaced with new brake pads.
When Should the Brake Pad Wear Sensor Be Replaced?
Replacement is recommended whenever:
- The brake wear warning light is illuminated.
- New front brake pads are installed.
- The sensor has contacted the brake disc.
- The wiring has become damaged.
- Corrosion affects the electrical connector.
- During routine brake servicing.
- As part of a complete front brake overhaul.
Replacing the sensor at the same time as the brake pads ensures accurate future wear monitoring and avoids unnecessary labour costs.

Fits Left or Right. Supplied individually as one wire sensor. Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The sensor forms part of the vehicle's electrical pad-wear warning system, indicating when brake pad wear requires attention. It is a monitoring component, not a replacement for inspecting the pads and discs.
Functions
- Provides a pad-wear detection connection.
- Supports the dashboard brake-wear warning.
- Replaces a worn or damaged sensor wire during brake servicing.
Technical Details
- Supplied diagram reference: 99160918100; component identified as a sender wire or pad wear indicator.
- Diagram quantities are two wherever stated; these are assembly requirements, not the supplied pack quantity.
Symptoms of Fault
A brake-wear message remaining after pad renewal, damaged wiring or broken retaining clips warrants inspection. A warning can also indicate genuinely worn pads, so establish the cause before replacing the sensor.
Why Replacement Matters
Renewing a worn or damaged sensor supports correct operation of the pad-wear warning system. Assess the sensor, connector and cable routing during pad replacement rather than assuming an existing wire can be reused.
FAQs
Is this an axle set?
No. One sensor wire is supplied; several diagrams specify two for the assembly.
Does it fit every 991 brake system?
No. Check the model, production details and brake equipment, including the PCCB (I450) restrictions where stated.
Should it be renewed with the pads?
Plan to assess the sensors during pad servicing and replace any that are worn, damaged or unsuitable for reuse.
