For the second time in 16 months/10K miles I just had to replace my front disc rotors (as well as the pads) because they were too rusty ('98 Saturn SL2, 120K miles). The car is now typically driven 1 day a week and sits outside. How can I keep this from happening again? For best mileage and least wear and tear, I was taught to brake gently -- have I babied my brakes too much? Do I need to make sure I brake really hard (just short of lockup) once a day, to wear off the light rust before it gets too deep? Is there a better way? Is my only hope to clean out the garage and park inside?
