One problem related to brake disc caliper has been reported for the 1999 Chevrolet 1500. The most recently reported issues are listed below.
Backing out of my driveway the brake pedal went to the floor, the rear brake lines rusted through. To do the repair the rear calipers needed to be replaced because the both the bleeders and line connections were seized. Flash forward one year and now the front lines front hoses and front calipers need the same thing.
