How long do front and rear wheel brake rotors typically last on 335i
How long do the front and rear disc brakes last on the 335i. I am aware that you are to check for discoloration, scoring, etc and disc thickness. But for example, typically should the front or rear discs be changed every time the pads near changing? Or do the front discs usually get replaced every other brake pad change? Just wanted to get an idea on frequency.
