Detailed Description

Carlson 19123 is a replacement disc brake pad wear sensor for Mercedes-Benz vehicles equipped with wear-indicator style brake systems. When the brake pads wear down, the sensor frays and triggers the warning system so the driver knows service is needed.

This part cross-references OE-style wear sensor applications for the same use case.
