Steering wheel vibration under moderate braking

[Geraint Lloyd]

would add track rod end (tie rod end) ball joints, or the bushes on the track rods at the rack end, to this list for a 200 TQA for example

light braking getting shudder / vibration (clunking like) was worn bushings 
in the suspension.

moderate braking getting shudder / vibration

Heavy braking resulting in  MASSIVE wheel shimmy is usually warped rotors or 
brake faded rotors.

Any light braking that grabs then lets go to grab again is a warped rotor.

Drag the brakes at 10 MPH to check.

I took a Chevy Malibu and fadded the brakes in 1 1/2 laps at NHIS, which 
resulted in massive wheel shimmy.  Cooled down the return trip was smooth braking.

Also make sure your guide pins aren't frozen resulting in uneven pad wear.
