Monitor brake-pad wear on your Mercedes-Benz with the Carlson Disc Brake Pad Wear Sensor, MPN 19126. It installs at the front position as a direct-fit replacement for the 2009-2018 Mercedes-Benz G550 [All]. This electronic sensor rides with the brake pad; as the friction material wears down, the sensor element frays and completes the warning circuit, signaling the driver that the pads and hardware need attention.
- Electronic wear indicator: Frays as the pads wear to notify the driver when the brake pads and hardware need changing.
- OE-quality build: Matches Original Equipment (OE) quality specifications and is built with quality materials for proper function.
- Connector details: 34-1/8 in wiring harness with 2 male pin-type terminals and 2 male connectors.
- One-time use: Cannot be reused after pad replacement — install a new sensor with every pad job.
The listed G550 application uses two sensors, so order 2 for a complete replacement. Country of origin: China.
