I wouldn't say this is so much bad service as it is shop prices. With my accord I often went to Pepboys for diagnostics then performed the work myself. They quoted me around $1k for new pads and rotors, but i bought the parts and tools for under $200. It was a massive pain in the ass, but the accord was no longer worth fixing at a shop. I'd say you're being ripped off if they charged for services they didnt perform or werent needed.
