When to replace brake rotors

the same rotors have been on my Ford for over 175,000 miles(front and rear)! you shouldn't have to replace them unless a caliper sticks or pads dig into them. get 2nd opinion or if no trouble with them,drive on! The Dealer has FORK-ED tongue sometimes!

Jusk ask them how thick they are and what the factory minimum thickness is. If its above that and they aren't warped or rusted badly you should be able to go longer especially since they are in the rears. Alex
