brake shudder

[pistonbroke]

Can anyone help me diagnose shuddering front brakes, with steering wheel wobble.
Replacing the discs and pads did very little.
Replacing worn front suspension made the symptom feel different, but the shudder and wheel shake is still very much there.A used(but good) rack went in as well as tierods,lower control arms and bushes.
The only suspension component not changed was the ball joint at the bottom of the strut. They seemed servicable but could that be the culprit?
Only other thing I can think of is worn bushes in the calipers where the guide pins go.
All ideas welcome!!

Do you get this only at certain speeds? (Maybe more when applying the brakes at higher speeds) The problem may be one of your front wheel hubs (or both). Also, check your sway bar links.

Don't think it's hubs. Put a dial gauge on the new discs to check for runout and got 0,10mm even if I lever on the disc, so hub bearings seem ok.

Sorry DRZ. Did not answer yr question. Happens all speeds but worse at higher speeds.

Checked the hubs again ,this time with the wheels on . Rocking in the 12/6 o'clock position shows no play on the left, but there is some play on the right. This did not show up when I had a dial gauge on the disc, but the leverage rocking the disc is obviously less.
Impossible question to answer--how much play is too much?!?
