Product Details
This PowerStop rear Euro-Stop electronic brake wear sensor is designed for 2001-2006 Lexus LS430 rear brake applications. It is intended to replace a worn or damaged sensor so the vehicle’s brake wear monitoring system can continue to report pad condition accurately. The SW-0904 uses a square female connector, blade terminals, and a two-wire layout to match the original sensor style used on the application.
This part cross-references Beck/Arnley 084-1728 and Raybestos Brakes WK1537 for the same application.
Common Reasons to Replace
- Brake wear warning light remains on after pad service
- Damaged sensor wiring during brake pad replacement
- Corroded or heat-aged rear wear sensor connector
- Intermittent pad wear signal on the Lexus LS430
- Restoring rear brake wear monitoring after rotor and pad service
Installation Notes
Install SW-0904 on the rear brake position only. Inspect the connector, grommets, and harness routing before installation, and confirm the sensor seats correctly in the brake pad assembly. For best results, replace the sensor during rear brake service on the Lexus LS430 rather than reusing an aged or damaged unit.
Quality Assurance
PowerStop designs Euro-Stop brake wear sensors to meet OEM-style requirements for fit and function, with construction intended to withstand elevated brake temperatures and maintain conductivity over extended use. Compatible With 2001-2006 Lexus LS430 rear brake wear sensor applications.
