Wobble under braking???? HELP!!!

[Tom Tom Turbo]

Okay, this is starting to pi$$ me off! My T-Type has a decent wobble under braking and I am lost as to what it can be. The car has brand new Michelins (around 600 miles) and the tires were balanced and all that stuff...it has new pads, rotors, and lines/fluid. The only thing that I haven't replaced is the shocks! Could it be the proportioning valve or something along that line?? Oh, I have also replaced the master cylinder/power booster thingy. Anybody have an idea????

Warped rotors or possibly a bad wheel bearing. Lug nuts tight?

Have you replaced the upper contol arm bushings? The bushing under the downpipe gets cooked and under braking the arm can move around enough to result in weird tire movements.

bearings were replaced and the rotors were checked for straightness. They both checked out good. I'm starting to think it could be proportioning valve not sending enough brake fluid to either side. Would that cause it????
