Took my 08 sierra to dealer because I thought I had a caliper hanging up. Left front I could hardly spin by hand and the right spun freely. Checked rotor temps, left was 130, rt was 98. Left front also squeeks until the brake is applied. Dealer said brakes were fine and the left front will spin harder because the axel is always engaged is not on the right and thats normal. they also said rotor temps were fine. I'm almost out of warrenty and need to get this resolved soon.
