PowerStop SW-0442 Disc Brake Pad Wear Sensor - Front

Front Euro-Stop Brake Wear Sensor

PowerStop SW-0442 is a front disc brake pad wear sensor for select BMW applications. It is built to match the original sensor’s form, fit, and function, with materials selected to handle high heat and maintain reliable electrode conductivity over long service intervals.

For BMW X3 and BMW X4 front brake service, replacing the wear sensor at the same time as the pads helps restore proper brake wear monitoring and avoids reusing a worn electrical component. The PowerStop Euro-Stop line focuses on OE-style replacement parts for straightforward brake maintenance.

Key Features

• Front electronic brake wear sensor for disc brake pad monitoring
• OE-style form, fit, and function for direct replacement use
• Built to withstand extreme temperatures
• Gray connector with oval shape and female connector design
• 2-wire harness with pin terminals and integrated grommets
• Cross-reference part numbers include Beck/Arnley 084-1914 and Raybestos Brakes EWS134

Detailed Description

PowerStop SW-0442 is part of the Euro-Stop brake wear sensor line, a product line focused on replacing worn electronic pad sensors with OE-style components that match the original vehicle setup. This front sensor is designed for BMW brake systems that use electronic pad wear monitoring, helping maintain accurate wear indication after brake service. It is engineered for durability in high-temperature brake environments and continued conductivity over extended mileage.

Fits 2015-2018 BMW X4, front. Fits 2011-2017 BMW X3, front. This part number, SW-0442, is a direct-fit replacement for select front brake wear sensor applications on BMW X3 and BMW X4 models.

What It Helps Address

• Brake wear warning light remaining on after pad replacement
• Damaged or brittle original wear sensor wiring
• Inaccurate pad wear monitoring at the front axle
• Sensor faults caused by heat exposure and age
• Brake service resets that require a new electronic wear sensor

Installation Notes and Tips

Install SW-0442 at the front brake position only on the listed BMW applications. Inspect the sensor routing, connector, and grommets during brake service to confirm the harness seats correctly and follows the original path. Replace the sensor when the original unit is worn, damaged, or triggered by pad wear.

Quality Assurance

PowerStop states that its Euro-Stop brake wear sensors are built to meet or exceed OEM requirements and are tested for reliable operation in demanding brake temperatures. The SW-0442 is engineered as an OE-style replacement for consistent fit and function on the specified BMW front applications.
