[urq] Doing the brake shake...not a dance I enjoy!

[Ingo Rautenberg]

Hmm.  New sway bar bushings?  Are these 'new' brake pads?  Maybe switch the
pads from side to side.  Since you sy the car is fine until you've braked a
few times (warming things up), I would think it has to do with something
that is heating up.  Even if the brake proportioning was messed up, it
should not result in front-end shake, IMO.

Please do let us know what you find out.  Also, Some tires when they warm up
can get out-of round -- in which case a balancing of the tires on one of the
newer dynamic road load balancing machines might help.  This is the one
(Made by Hunter IIRC) that runs the tire against a cylinder to simulate
driving force load.

Additional info:

Brakes bled by Bentley procedure.  New strut inserts, bearings in
February...pre Steamboat, no ill affects from Steamboat on return drive
to Orlando, or for several weeks after..

Justin,

OK, then! The fact that this only happens once you've heated up the
brakes
makes me think you're on the right track.  Suggest a brake bleed while
you're at it and check to see if one wheel is appreciably warmer than
the
other (sticky caliper when warm syndrome).

Other things you may want to check:
First.  Either swap the tires front to rear to rule wheels/tires out.
Second:  Check for wheel beearing play -- if you've got a lot of free
play,
it may not be noisy, but may give you that symptom when braking.
Third:  I know you hate to hear this -- replace front strut bearings.
Fourth:  Worn strut inserts

At least those would be the areas I'd be looking at.

HTH
