Thanks for the quick reply. This is what I found out. I loosened the caliper
bolts enough to grab the slider/spacer piece with pliers. They all rotated
freely.

HLS mentioned about using the parking brake for adjustment. I knew about
this and usually use the parking brake. To try to fix the problem, I set and
released the parking brake several dozen times but it made no difference.

With two lug nuts holding the rotor tight to the hub, I used a pry bar to
move the caliper out so that the inner pad was touching hard on the rotor. I
measured a gap of .036 on the drivers side and .025 on the passenger side
between the outer pad and rotor. Is this normal? The outer pad on the
passenger side has twice the wear as the other pads.
