Is the most likely culprit uneven/warped rotors? Other than that, what else causes steering wheel shake when braking, but not otherwise? I can feel vibration through the brake pedal as well. Same issue observed on two different sets of wheels/tires. FYI, this is on my 530i. Front brakes are pretty old (last replaced 12 years and 70K miles ago), but look fine to the naked eye, other than some surface rust. I am leaning toward getting new brakes first and seeing if that fixes it. But in case it doesn't, what else should be looked at?
