I have a vibration in the brake pedal when braking, which is only worse when braking hard. I know the rotors (front) were turned to the min amt last brake job. So I do need new ones; the more worn they are... does this mean they are more susceptible to warpage? (I know that didn't make sense, I'm tired.)
I also had my lower control arm bushings replaced recently.. but still hear popping (might be related to something else also, concurrently, IE, could be 2 things). I have a worsening vibration in the steering wheel also, which is also worse when braking hard. I just had new tires put on 3,000 miles ago, which were balanced. Also had a 4 wheel alignment a few thousand miles ago when I got the bushings replaced.
Wondering if most of this might be some how related?

Anyway, does vibration in the brake pedal most likely mean that the rotors are warped? Thanks a bunch.

Taking the car in to have them recheck bushings and alignment, and to check for a possible loose drivetrain mount (mount, flex disc, etc.). Will be nice cruising in the CLK Cabrio... TOP DOWN!
