PowerStop SW-0704 Disc Brake Pad Wear Sensor - Rear

Rear Euro-Stop Brake Wear Sensor

PowerStop SW-0704 is a rear electronic disc brake pad wear sensor for select Audi, Porsche, and Volkswagen applications. It is built to match OEM form, fit, and function, with temperature-resistant construction for consistent conductivity over long service life.

The PowerStop Euro-Stop line focuses on direct-fit brake wear sensors for European vehicles, making it a practical choice when replacing worn rear brake pad sensors during brake service.

Key Features

• Rear disc brake pad wear sensor for electronic brake wear monitoring
• Direct-fit replacement designed to match original OEM dimensions and connector style
• Built to withstand extreme temperatures for stable electrode conductivity
• Black/red connector with oval female connector and blade terminals
• Two-wire design with a 9.842 in. wiring harness length
• Compatible with select Audi Q7, Porsche Cayenne, and Volkswagen Touareg rear brake applications

Detailed Description

PowerStop SW-0704 is a rear Euro-Stop electronic brake wear sensor engineered for vehicles that use a pad wear warning system. It is designed for direct replacement on 2007-2011 Audi Q7 rear applications, 2012-2015 Audi Q7 rear applications except ceramic composite brakes, 2003-2004 and 2008-2010 Porsche Cayenne rear applications, 2005-2006 Porsche Cayenne rear applications with 330mm or 358mm rear rotors, and 2004-2010 Volkswagen Touareg rear applications with the listed rotor configurations. This part number, SW-0704, is intended to restore proper brake wear monitoring after sensor replacement during pad and rotor service.

This part cross-references Beck/Arnley 084-1540 and Raybestos Brakes EWS113 for the same application.

What It Helps Address

• Brake wear warning light triggered by a damaged rear sensor
• Intermittent pad wear signal from heat-damaged wiring or terminals
• Sensor failure after rear brake pad replacement
• Loss of brake wear monitoring on Audi Q7, Porsche Cayenne, or Volkswagen Touareg rear brakes
• Connector or harness mismatch when replacing an OE-style rear wear sensor

Installation Notes and Tips

Replace the rear wear sensor whenever the original sensor is worn, damaged, or removed during brake service. Verify rotor size and brake package on Porsche Cayenne and Volkswagen Touareg applications, since fitment varies by rear rotor configuration. Confirm the connector shape, terminal style, and harness routing before installation. SW-0704 is a rear-position sensor only and should be matched to the vehicle’s original electronic wear sensor layout.

Quality Assurance

PowerStop designs Euro-Stop brake wear sensors to meet or exceed OEM requirements and to maintain performance under high-temperature brake conditions. The SW-0704 is built for long-term operation and consistent conductivity in the rear brake wear monitoring system.
