Rotors for some cars are indeed small and light enough they should be replace with each set of pads. Ours are not those. You should easily get 3 sets of pads or more out of a set during normal driving.

"For normal usage conditions, the design*life of the front wheel brake discs should be equivalent to the useful life of two sets of*corresponding brake pads. Some discs may have a shorter useful life, because they*have been designed to achieve specific targets."
NORMAL driving. That does not mean driving it as a Prius it means driving it as it should be on the public streets.
