The EBC EFA178 front brake pad wear indicator lead is a genuine replacement component designed to monitor brake pad wear and help maintain dependable braking system performance. As the brake pads approach their service limit, the wear sensor activates the vehicle’s warning light, alerting the driver that brake inspection and pad replacement may be required. Replacing the lead when servicing the brakes helps restore proper warning-system operation and supports timely maintenance.
Designed for brake applications using FMSI pad number D1694, this EBC wear lead sensor kit is made for vented brake systems with five bolt holes. It features a 11.6-inch diameter, 2.0-inch height, and 1.1-inch thickness. The component is intended for front brake service on select Mercedes-Benz vehicles and provides a direct-fit solution for replacing a worn or activated brake pad sensor.
The EBC EFA178 helps preserve the functionality of the brake wear monitoring system without unnecessary modifications. Before ordering, verify vehicle year, model, brake configuration, and pad application to ensure proper fitment. This sensor is listed for select 2014-2016 Mercedes-Benz CLA250, 2015 Mercedes-Benz GLA250, 2015 Mercedes-Benz C300, and 2015 Mercedes-Benz C400 applications, including vehicles equipped with compatible FMSI D1694 brake pads.
