Installed four new rotors and pads on the f10 535i at 49k miles. It was pulsing badly and the rotors were visibly rusty. I used Zimmermann rotors and I think Textar (OEM-equivalent) pads. After a few thousand miles, the pulsing is coming back.... To top it off, I'm feeling very slight pulsing on the Boxster (at 17k miles).
Could bad roads (braking on bumps e.g.) cause issues over time? I see a commonality among Rumatt, Terry and I and that's where we live and drive.
I'm paranoid about holding down the brake pedal at a stop, will occasionally use hand brake or move car a bit to avoid hot spots.
