** Use of the E-Brake is recommended for proper operation of the self-adjusting mechanism. **

NOTE: These rear GM calipers use the parking brake to maintain proper brake adjustment, as the parking brake is integrated into the caliper and helps adjust the piston when there is clearance between the inboard brake pad and the rotor. Regular use of the parking brake allows the internal clutch in the caliper piston to take up this clearance and keep the rear brakes properly adjusted. Without periodic use of the parking brake, rear brake adjustment may decrease over time and result in a lower or softer brake pedal feel.

The caliper piston pin needs to be aligned with the notch in the pad to avoid fitment issues.

Fit as expected with exception to the connection. Also needed to buy a banjo to AN-4 adapter. The GM calipers being replaced appeared to have an NPT port and not the banjo type.
