ACDelco 84945113 Rear Disc Brake Pad Wear Sensor

The ACDelco 84945113 is a GM Original Equipment rear disc brake pad wear sensor designed to monitor brake pad thickness and alert the driver when brake pads require replacement. This genuine GM component is engineered to the same specifications as the original factory-installed sensor, ensuring accurate wear detection and reliable performance.

Key Features:

• GM Original Equipment quality for precise fit and function
• Monitors rear brake pad wear and triggers dashboard warning light

Brake pad wear sensors are critical safety components that provide early warning of brake pad deterioration. When the sensor detects that brake pads have reached their minimum thickness, it completes an electrical circuit that illuminates the brake warning indicator on the instrument panel, prompting timely maintenance before brake performance is compromised.
