What is the condition of the rotors? New or at least re-surfaced? Most brake
squeals are the result of friction irregularities between the rotor and
pads. This can be from the rotors not turning true or the surface being
glazed or worn unevenly or having surface irregularities. One thing with
disc brakes is that the outer diameter of the rotor is actually traveling
faster than the center. The pads design and mounting has to take this. The
sequel is the pads oscillating and chattering. Silencing shims can be the
best defense. There are now also piston cushions available to fit between
the piston and inside pad.

If the rotors were not replaced or at resurfaced I would begin there.
Remember the where limit is 13mm for these. If near or below that thickness
time for replacement.

Hey listers-  You know you should be camping with the kids instead of
reading this email.  But since you are, here is the question. Why do our
front brakes still squeal?  We have replaced the pads (twice).  This time we
put the GoWesty ones with the tapered edges.  We have tried the brake
treatment spray.  It works for a few days and then we are back to squealing.
They stop us just fine, but they scream like crazy when we apply them.
Tired of turning heads and making folks think we are running on the wear
indicators!
