Detailed Description

PowerStop SW-1660 is a rear Euro-Stop electronic brake wear sensor designed for BMW X3 models from 2018-2024. It is intended for vehicles that rely on an electronic pad wear warning system, helping maintain accurate brake service alerts after rear brake pad replacement. The sensor uses a 2-wire layout, a single oval connector, and a pin-style terminal design to match the original equipment configuration.
