Have a buddy in Tallahassee whose 2002 Tahoe has been diagnosed with a dragging rear brake - interwebz says it's a disc setup. Shop wants to replace the claipers. This has happened to me once or twice on other GM products and the fix was to re-grease the caliper slide pin. Easy, easy to do. May as well throw a set of pads on while you're in there.
Unfortunately, his SWMBO isn't keen on him working on their cars (he has tools but lacks experience), so I'm asking if anyone would please, please offer to help him out with the job or recommend an honest shop. He has tools but lacks experience. I'll vouch for him being a good guy - could anyone help either way?
