Product Details

PowerStop’s Euro-Stop Electronic Brake Wear Sensor line is focused on OE-style replacement parts for brake service. The SW-1218 follows the original sensor layout and connection style so it can be used when replacing worn brake pad wear sensors during brake maintenance. For drivers servicing Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, or GMC Sierra 3500 HD brake systems, this sensor supports the warning circuit used to monitor pad wear and help maintain proper brake service intervals. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake wear warning light triggered by a damaged or worn sensor
• Broken, brittle, or heat-damaged sensor wiring
• Incorrect wear sensor readings after brake pad replacement
• Service issues caused by an OE-style connector mismatch
• Brake maintenance on monitored front or rear brake applications

Installation Notes

Replace the wear sensor whenever the brake pads and related sensor are serviced, especially if the original sensor shows heat damage, connector wear, or wire fatigue. Verify connector shape, terminal style, and harness routing before installation. Confirm the vehicle position and brake package against the fitment list for 2020-2025 Chevrolet Silverado 2500 HD and Silverado 3500 HD, as well as 2020-2025 GMC Sierra 2500 HD and Sierra 3500 HD applications.

Quality Assurance

PowerStop designs Euro-Stop sensors to match OEM form, fit, and function and to meet or exceed OEM requirements. The sensor construction is intended to withstand extreme temperatures and maintain conductivity over extended service life.
