Product Details

PowerStop’s Euro-Stop Electronic Brake Wear Sensor line is focused on direct replacement for vehicles that rely on electronic pad wear monitoring. SW-0429 is engineered to meet or exceed OEM requirements, helping preserve the warning system’s ability to report pad wear as the brake pads thin over time. This makes it a practical choice for rear brake service on BMW 528i, 535i, and related rear applications where the sensor is part of the maintenance cycle.

This part cross-references Beck/Arnley 084-1534 and Centric Parts 116.34029 for the same application.

What It Helps Address

• Brake wear warning light staying on after pad replacement
• Damaged or brittle rear brake wear sensor wiring
• Faulty pad wear signal on BMW rear brake systems
• Loss of continuity caused by heat and road exposure
• Incomplete brake service when the wear sensor is not renewed

Installation Notes and Tips

Replace the rear wear sensor during brake pad service whenever the original sensor is worn, damaged, or triggered. Verify connector style, harness routing, and rear position before installation. Confirm fitment for your exact BMW model and year, including 2004-2010 BMW 525i, 530i, 528i, 535i, 550i, 645Ci, 650i, M5, and M6 rear brake applications.
