Bowa 906 540 15 17 Disc Brake Pad Wear Sensor - 906 540 15 17

The Bowa 906 540 15 17 is an electronic disc brake pad wear sensor designed to monitor brake pad thickness and alert drivers when replacement is needed. This front-position sensor uses a wire loop with electrical resistance to detect when brake pads have worn to a critical level, illuminating a dashboard warning light before the pads become unsafe.

Key Features:

• Electronic wear detection system eliminates guesswork about brake pad condition
• Designed for front axle installation on select Mercedes-Benz Sprinter and Metris models
• Uses resistor circuit technology to monitor pad wear and trigger dashboard warnings
• High-temperature resistant materials withstand brake system operating conditions
• Direct plug-in design with vehicle-specific connectors for easy installation
• No core charge required for hassle-free replacement

How It Works:

This sensor mounts near the brake pad with a wire positioned close to the rotor surface. As the brake pad wears down, the rotor eventually contacts the sensor wire, breaking the circuit and changing the electrical resistance. This triggers the brake pad wear warning light on the instrument cluster, alerting the driver that brake service is needed. The sensor is designed to wear out along with the brake pads and should be replaced during every brake pad replacement.

Interchange Information:

This Bowa sensor cross-references with OEM part numbers A1680002 and 52433029099 (524 33029 099). Alternative part number format: 9065401517.

Brake pad wear sensors are critical safety components that help prevent damage to rotors and ensure optimal braking performance. Replacing worn sensors during routine brake service maintains proper system monitoring and driver awareness of brake condition.
