About the Raybestos R-Line Product Line

The R-Line by Raybestos represents a dedicated product line focused on delivering reliable brake components tailored for specific vehicle applications. The R-Line disc brake pad wear sensors, including the EWS240, are engineered to meet the exact specifications required by Porsche models such as the 718 Boxster, 911, and Boxster.

Installation of the Raybestos R-Line EWS240 sensor should be performed by a qualified technician familiar with Porsche brake systems. Ensure the sensor is properly connected to the brake pad assembly and the vehicle’s electrical system. Verify sensor functionality by checking the dashboard warning light after installation. Always replace brake pad wear sensors in pairs to maintain balanced brake system monitoring.
