[T3] Brakes & Front End

[J. Jonik]

Lug nuts are snug, and so are wheel bearing nuts...adjusted Just Right.   Outside edges of both tires, left and right, are wearing smooth though.  Just barely passed inspection on that.   Maybe rusty front end support beams, maybe sagging, don't permit proper alignment, etc?   But....does that affect braking and that noise and vibration? 
Still, there's that  bump bump when braking AND, just discovered today, the car pulls to the left when braking if steering wheel left to its own.   Again, all rotors SEEM to be ok...but not put on any equipment to check.
  It's a real bump-bump braking thing up front somewhere.   Could that Slightly Wiggly left tie-rod-end be part of, or cause of, this?     But what's that got to do with braking?

Doesn't really sound like a master cylinder problem. How about the tires?

Jack up the front end and watch each tire tread from the front as you spin it.
