There is abnormal brake rotor deteriation and rusting due to poor manufacturing or steel formulas which rust accerlerates and wears down the pads unevenly. I have worked on brakes on many autos and a few trucks I've owned over the last few decades and never have seen such rusting and surface flaking of the disk rotor on my vihicle. I had my dealer look at the rotors and they agreed it may be a bit excessive. I have to replace all four rotors due to poor quality and unrepairable rotors. The rotors look like they came off a 20 year old truck. . . . This is a safety and quality problem that should be looked into. Thank you.
: the contact stated when the brakes were depressed there was a loud grinding noise. While the vehicle was being inspected, the dealership noticed the rotor had a 1" wide and 3" long gauge in the metal about â¼"deep. The contact determined this was due to porosity. The dealership informed the contact this was normal wear and tear on the rotors.
