when I replaced the rotors/pads/rear calipers they looked still good. OEM GM PADS . rotors had a smoothed non grooved surface.the rotors where 10 yrs old rust holes on all begining to show.

the replacement rotors/pads/calipers advance auto parts life time warrantee. going on 3 yrs still working great.

with drums these parts are in most cases chinese junk. soft metal/ very soft. also using a higher grade pad of the correct material for the vehicle will determine proper brake effort and min rotor/drum wear.

with the soft metal used today best pay for the higher quality lifetime warrantee. bring in the worn out parts walk out with new total cost a few hours work. even the brake pads are free !
