How It Works

This brake pad wear sensor monitors pad condition through the brake caliper connection and wiring harness on the listed Cadillac Escalade, Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Sierra 1500, and GMC Yukon applications. Standard Ignition PWS383 is used to restore the wear-signal circuit when the original sensor or connector is damaged, worn, or no longer reading correctly.

Common Problems It Can Address

• Brake pad wear warning light stays on
• Brake wear indicator does not trigger correctly
• Damaged front left brake caliper sensor connector
• Broken or corroded wiring harness connection
• Intermittent pad wear signal on covered GM trucks and SUVs

Installation Notes

Install at the front left brake caliper location and verify the oval female connector and 2-blade terminal interface match the vehicle harness before service. Inspect the brake pad wear circuit, connector condition, and routing near the caliper during replacement to help confirm a secure electrical connection.

Quality Assurance

Standard Ignition supplies electrical and sensor components for automotive service applications, and PWS383 is built to match the listed OE-style fitment requirements for the covered vehicles.
