Bowa A083011 Brake Pad Wear Sensor for Mercedes-Benz

The Bowa A083011 is a high-quality brake pad wear sensor designed as a direct replacement for Mercedes-Benz OEM part number 1405401217. This essential safety component monitors brake pad thickness and alerts the driver through a dashboard warning light when brake pads have reached their minimum service specification and require replacement.

How It Works:

The brake pad wear sensor features a simple yet effective design consisting of a wire loop embedded in a protective housing. The sensor mounts to the brake pad and extends to the minimum pad thickness depth. As the brake pad wears down during normal use, the wire loop eventually contacts the brake rotor. When the rotor cuts through the wire loop, the electrical circuit breaks, triggering the brake pad warning light on your dashboard.

Key Features:

• Direct replacement for Mercedes-Benz OEM 1405401217 (also supersedes 1265402017)
• Manufactured by Bowa, a German company with OEM-quality standards
• Designed for front or rear brake applications depending on vehicle model
• Single-use component - must be replaced with every brake service
• Precision-engineered to meet or exceed original equipment specifications
• Quality materials ensure reliable wear detection and durability

Application Note:

This sensor fits various Mercedes-Benz models including R107, W115, W116, W123, W124, W126, R129, W140, R170, W202, W207, W209, W211, and W222 chassis from the late 1970s through the early 2000s. Common models include the SL, SLC, E-Class, S-Class, C-Class, and others equipped with brake pad wear monitoring systems. Always verify fitment for your specific vehicle year and model.

Installation Recommendation:

Brake pad wear sensors are designed as one-time-use components. Even if your current sensor appears intact, it should be replaced whenever installing new brake pads to ensure accurate monitoring and prevent false warning lights. Professional installation is recommended as part of a complete brake service.
