If the out of roundness and parallelism is okay-just the pads are needed to be replaced-

Many shops will recommend they be replaced because they are so inexpensive now that it costs more to machine the old used ones. That doesn't mean they MUST be replaced unless they will be below the minimum legal thickness after they're machined. Many new rotors are close to that legal limit now to save weight so they don't last the life of the vehicle like they did in the 1970s.
