How about the rear suspension parts?
if something like a ocntrol arm was able to "move" a bit, i would expect
the reverse of your problem of course - under power the part rests in
one position, when you hit the brakes it shifts and pulls. But you are
getting a pull when lifting off the brake - even if it is free enough to
move right back, paking that pull sensation, one would expect the
opposite of that pull upon first braking.
So I may be barking up a wild goose canyon here.
You may be on track with the sticky caliper idea - it comes away
eventually while driving. You brake, all is ok, as in all calipers
close and grab. You lift off the brake, and one caliper *does not* let
go right away, and pulls to its side.
usually sticky calipers make a "hot" wheel (hot to the touch after
driving) but if yours is letting go soon enough it might not heat up
Maybe someone else will have something more constructive to offer?
