Keep tabs on brake pad wear with the Standard Ignition Disc Brake Pad Wear Sensor PWS383. This sensor mounts in the front-left brake caliper position and drops in as a direct-fit replacement for the listed applications, including the 2021-2023 Cadillac Escalade and Escalade ESV, 2019-2023 Chevrolet Cheyenne, 2019-2023 Chevrolet Silverado 1500, 2022 Chevrolet Silverado 1500 LTD, 2021-2023 Chevrolet Suburban and Tahoe, 2019-2023 GMC Sierra 1500, 2022 GMC Sierra 1500 Limited, and 2021-2023 GMC Yukon and Yukon XL (engine: All) — see the Buyer's Guide tab for the full list.
As the friction material wears down, the sensor's circuit is designed to signal the pad-wear warning on the dash, prompting timely inspection. If a damaged or worn-out original sensor is triggering (or failing to trigger) that warning, this replaces it.
- Glass-reinforced plastic resin: resists extreme temperatures and environmental conditions.
- OE-matching connectors and terminals: intended to make a water-tight connection to the wire harness.
- Protective sleeve: helps prevent wire chafing and short circuiting.
- Harness grommets and wire clips: support proper mounting and routing within the chassis.
It uses a single oval female connector with two male blade terminals and mounts at the brake caliper. Country of origin: Mexico.

Frequently Asked Questions
What does this brake pad wear sensor do?
It monitors disc brake pad wear. As the friction material wears down, its circuit is designed to trigger the dashboard pad-wear warning so you know to inspect the brakes.
Which vehicles does the PWS383 fit?
It's a direct-fit replacement for applications such as the 2021-2023 Cadillac Escalade, 2019-2023 Chevrolet Silverado 1500, 2021-2023 Tahoe/Suburban, and 2019-2023 GMC Sierra 1500. See the Buyer's Guide tab for the full list.
Where does this sensor mount?
It installs in the front-left brake caliper position, as listed in the catalog for the covered applications.
What interchange numbers does it replace?
It cross-references WS583, 84618533, and 84886785. Its own manufacturer part number is PWS383.
Will replacing this sensor clear my brake wear warning light?
If a faulty or worn-out sensor is the cause of the warning, replacing it addresses that. If the pads themselves are worn, service the brakes and diagnose the circuit before assuming the sensor is at fault.
