Brake Disc Caliper problems of the 2002 Chevrolet C1500

Vehicle had grinding noise from rear wheels and loss of power. Rear brakes failed with 9, 975 miles on vehicle. Dealer found right rear brake caliper rusted solid and not operating, causing inner right disk brake pad to wear out prematurely. Was advised that this was a result of the vehicle not being used enough, allowing components inside the caliper to rust. Dealer rebuilt right rear calipers, turned down both excessively rusted rear rotors and replaced rear disc brake pads.
