Sometimes the brake caliper needs to be disassembled, cleaned, and relubricated. Not difficult to do, just keep track of every item as you take it apart.
+1 Need a small sized cone wrench to hold the caliper centered while you tighten the bolt. Park actually makes one for it.
Invest in a digital caliper, you can find them on sale at places like Harbor Freight as cheap as $10. That will save a lot of returning parts and reordering something different.
