There may be a squeal or tick (rotational type noise) heard coming from the front brake calipers when the brakes are not applied on some 2023-2026 Colorado and Canyon trucks. (Fig. 6) In addition, the front brake pads may appear to be wearing unevenly.
Fig. 6
The brake sound and pad wear conditions may be due to a missing front brake caliper spring or an incorrectly positioned front disc brake pad retainer. (Fig. 7)

Inspect the front brake assembly and if the front brake caliper spring or the front disc brake pad retainer spring is not positioned correctly, reinstall the caliper spring or the front pad retainer spring in the proper location. With the spring correctly positioned, recheck if the sound occurs with the vehicle moving and the brakes not applied.
If the front brake caliper spring is missing, or if the front brake pad thickness on one or both pads is less than 7mm, replace the front disc brake pads.
Ensure that the front brake caliper spring and front disc brake pad retainer spring are positioned correctly when installing the new brake pads. Install the front disc brake pad retaining spring with the three-tab side first. (Fig. 8. 1. Front brake caliper spring; 2. Front disc brake pad retaining spring)

The front brake caliper spring should be installed in the correct holes in the front disc brake pads. (Fig. 9)
