Detailed product overview

The PowerStop Euro-Stop line focuses on brake service parts that follow original equipment specifications for form and function. SW-1509 is designed for applications that require a disc brake pad wear sensor, helping maintain proper wear-indicator operation as brake pads age. The harness length, connector style, and terminal layout are specified to align with the original sensor design used on the supported Mercedes-Benz, Dodge Sprinter, and Freightliner Sprinter applications. If you are replacing a worn sensor during brake pad service, SW-1509 provides a direct-fit solution for the listed vehicles.

This part cross-references Beck/Arnley 084-1525 and Raybestos Brakes EWS114 for the same application. Use SW-1509 when servicing brake wear monitoring on Mercedes-Benz G550 and Mercedes-Benz G500 models, as well as the Sprinter applications shown in the fitment table.

What this part helps address

• Brake wear warning light triggered by a worn sensor
• Damaged sensor wiring from heat or road exposure
• Incorrect wear-indicator readings after pad service
• Loss of continuity in the brake pad monitoring circuit
• Sensor replacement during brake pad maintenance

Installation notes and tips

Replace the worn sensor during brake pad service and verify connector style before installation. Confirm the vehicle uses the listed push-in type where noted in fitment, and route the harness to avoid contact with moving or hot components. Always compare the original sensor connector and terminal layout to SW-1509 before installation.
