This sounds like the best bet. Closest firestone wants $950. If I can free up the caliper then everything else should be smooth sailing.

Can I replace one pad and do the rest later or will it throw everything off?

I just want to get home and replace everything with premium parts.

they are dissimilar. one side is within tolerance since the last service 45k Go

This is an 08 chevy 2500 runs great, was my fathers, but were at 180k and and I know she could be running smoother

i took one out to inspect. should i change wires too?
