• OEM-style form, fit, and function for Mercedes-Benz brake service
• Built to withstand extreme temperatures for stable electrode conductivity
• Designed for long service life after brake pad replacement
• Connector details include a black oval female connector with 2 terminals
• Wiring harness length measures 3.740 in. / 95.00 mm

Product Line Details

PowerStop’s Euro-Stop line focuses on brake service parts that match original equipment requirements for European vehicles. SW-0505 is part of that line and is intended for drivers replacing worn brake pad sensors during routine brake maintenance on Mercedes-Benz models.

Detailed Description

When brake pads wear down, the sensor should be replaced at the same time to keep the warning system working correctly. PowerStop SW-0505 is engineered as an electronic brake wear sensor for Mercedes-Benz rear applications and select front positions, including AMG, C-Class, E-Class, S-Class, SL, SLK, GLE, GLS, GLK, and Maybach models. This part cross-references Beck/Arnley 084-1526 and Centric Parts 116.35005 for the same application. If you are servicing a Mercedes-Benz AMG GT 63 rear brake setup or a Mercedes-Benz E350 front brake system, this sensor is built to match the original sensor layout and restore proper wear detection.

What It Helps Address

• Brake wear warning light staying on after pad replacement
• Inaccurate pad wear alerts from a damaged sensor
• Broken or brittle sensor wiring during brake service
• Loss of brake pad monitoring on Mercedes-Benz electronic systems
• Need for an OE-style replacement during rotor and pad maintenance

Installation Notes and Tips

Replace the wear sensor whenever the original sensor is worn, damaged, or triggered during brake service. Confirm the connector shape, terminal style, and harness routing before installation. This sensor is used in rear applications on many Mercedes-Benz models and in select front positions such as certain C-Class, E-Class, SLK, and S-Class configurations. Verify the exact position listed for your vehicle before ordering. For fitment examples, SW-0505 fits 2022-2026 Mercedes-Benz AMG GT 43, rear; fits 2013-2017 Mercedes-Benz E400, front; and fits 2008-2014 Mercedes-Benz C300, front.

Quality Assurance

PowerStop designs Euro-Stop brake wear sensors to meet or exceed OEM requirements for form, fit, and function. The sensor construction is intended to maintain conductivity under high-temperature brake conditions and support reliable wear monitoring over extended mileage.
