Product details
This Sebro sensor fits into the brake pad and connects it to the brake-wear warning circuit. The sensor style and axle matter: this reference is used at the front of selected 944s and at the rear of selected 911s with the older pin-type pad arrangement. Match the pad notch and electrical connection before ordering.
Technical Details
- Brand: Sebro
- Part reference: 94461221103
- Component: electrical brake pad wear sensor
- 911 applications require the corresponding sensor-notched brake pads; see the model notes below.
- Inspect the wiring and connector during pad replacement; a sensor damaged by wear or removal should be renewed.
