Power Stop SW-0421 Disc Brake Pad Wear Sensor

The Power Stop SW-0421 is a direct replacement disc brake pad wear sensor designed to alert you when your brake pads have reached their minimum thickness and require replacement. This critical safety component ensures you're notified before brake pad wear becomes a hazard, allowing for timely maintenance and continued braking performance.

Key Features:

• Direct OEM replacement designed to meet or exceed original equipment specifications
• Engineered to match factory form, fit, and function for easy installation
• Built to withstand extreme brake system temperatures for reliable operation
• Optimized electrode conductivity ensures accurate wear detection
• Durable construction for long-lasting performance over thousands of miles

Power Stop brake wear sensors are essential components for vehicles equipped with electronic brake pad monitoring systems. When the sensor wire makes contact with the brake rotor due to pad wear, it completes a circuit that triggers the dashboard warning light, giving you advance notice that brake service is needed. Always replace worn sensors when installing new brake pads to maintain proper system function.
