Peter may have it right (thanks for the thought, Peter). The pads do move a
bit in the calipers. I put more anti-squeal goo (blue goo from Permatex) on
the backs of the pads. The squeal and clunk went away. This is what
happened when I first installed the new pads. Maybe what is happening is
that the blue goo holds the pads while it's still gooey. When it dries, as
it always seems to do, the pads start moving.
Should the pads be able to move up and down in the calipers? I noticed that
the metal retaining clip arms are not evenly compressed against the pad
backing ends. The outermost arms (lowest and highest) press against the
pads, but the inner arms don't seems to be touching. This could allow the
pads to rotate slightly in the calipers, _maybe_. I guess the pads would
have the most motion if the brakes were applied during forward motion,
released at stop, and immediately reapplied in backwards motion (like when
I park against my brick stops in the garage).
Has anyone experienced this? Am I obsessing? (Though the clunk has not been
a constant with this car).
Thanks to all those who responded about possible looseness in the rear
cylinders. All circlips are present and accounted for, and the cylinders
have no more motion than when installed, though there is some motion, so it
could be part of the problem.
