Pagid 355250171 Disc Brake Pad Wear Sensor

The Pagid 355250171 is a disc brake pad wear sensor designed to monitor brake pad thickness and alert the driver when replacement is needed. This electronic safety component serves as a critical early warning system, eliminating guesswork and helping prevent brake failure due to worn pads.

How It Works:

The sensor features a wire loop with a low electrical current running through it. As the brake pad wears down, the sensor makes contact with the brake rotor surface, creating an open circuit that triggers a dashboard warning light. This electronic monitoring system replaces older acoustic wear indicators and provides more precise, reliable alerts.

Key Features:

• Direct replacement brake pad wear sensor from Pagid, part of TMD Friction Group
• Electronic wear detection provides accurate monitoring of brake pad thickness
• Triggers dashboard warning light when pads reach minimum safe thickness
• Designed to wear at the same rate as the brake pad for consistent performance
• Manufactured to OE specifications for proper fit and function
• Should be replaced whenever new brake pads are installed

About Pagid:

Pagid is part of TMD Friction Group, the world's largest manufacturer of original equipment brake friction materials. With nearly 100 years of brake technology expertise since 1925, Pagid supplies OE and aftermarket brake components to leading vehicle manufacturers worldwide, including Audi, BMW, Mercedes-Benz, Porsche, and Volkswagen.

Installation Note:

Brake pad wear sensors are designed to break during normal operation and should be replaced as a matter of course every time new brake pads are fitted. Heat exposure and installation work can damage sensor wiring and clips over time, making regular replacement essential for reliable brake monitoring.
