OK. How do you know this? What are your credentials? Tell us how many years you've made your living working on heavy vehicles and brakes. How many years have you been ASE certified? How many seminars have you attended, given by various brake part manufactures.

Good ole real life experience. I for one, knows that just because something is new (rotors) doesn't make it absolutely ready for service. They should be checked to ensure their true. No ase certification, no seminars. Just some things that I do.
Oh yea. Been around heavy vehicles and equipment for about 35 years now.
Commercial Class A license. DMV certified instructor.
So yea, I probably don't know too much.
