Detailed Description

Standard Ignition PWS350 is a brake pad wear sensor designed for vehicles that use an electronic pad wear indicator at the front caliper. The sensor uses a female oval connector and male blade terminals to match the original-style electrical connection, helping maintain proper wear signal communication between the brake system and the vehicle warning circuit. If you are replacing a front brake pad wear sensor on a Chevrolet Silverado 1500, GMC Sierra 1500, or a full-size GM SUV such as the Cadillac Escalade, this part number is built around the listed OE-style fitment.

Installation Notes and Tips

Install at the front brake caliper only on the listed applications. Verify connector shape, terminal style, and mounting location against the original sensor before installation.
