URO 928-612-313-04 Rear Brake Pad Wear Sensor

The URO 928-612-313-04 is a rear disc brake pad wear sensor designed for 1986-1989 Porsche 928 vehicles. This electronic wear indicator provides early warning when brake pads have reached their service life, illuminating a dashboard warning light to alert the driver before pad material becomes critically low.

Key Features:

• Rear brake pad wear sensor for Porsche 928 (1986.5-1988 USA/CAN models and 1986 ROW models)
• Compatible with both 16-valve and 32-valve engines
• Electronic sensor with wire loop design monitors brake pad thickness
• Completes circuit when pad wears to predetermined level, triggering dashboard warning
• Supersedes previous part number 928-612-313-02
• Fits chassis/VIN from 92GS8 61000 and up

Brake pad wear sensors are designed as single-use components and should be replaced every time brake pads are changed. The sensor wire is positioned close to the brake rotor and breaks when contacted by the rotor surface after sufficient pad wear, creating an open circuit that activates the warning system. URO Parts provides quality aftermarket replacement sensors that meet OEM specifications for reliable brake system monitoring.
