Our friends at Firestone Boston tried to scam me - very disappointing and infuriating. I took my car in for a standard oil change and was pleased to hear they looked at my brakes as a courtesy. I was told that my rotors, brake pads needed to be replaced & the calipers cleaned and adjusted - $450 estimate for all of this, at only 30,000 miles. I was suspicious, so took to another place for a second evaluation - rotors and pads just needed a quick clean-up - $80. Will never go back, recommend at least a second opinion if they do something similar to you.
