Hey. I need to finally get around to replacing the pads and rotors on all 4. Got Bosch Quietcast pads and AC Delco rotors. A little confused about the "break in" procedure. I'm supposed to drive it up to 30mph then slam on the brakes to 15mph and do this up to 10 times. And repeat again from 50mph to 15 10 times? Sounds like this will destroy the brakes! Is this procedure correct? Never heard of this.
