After inspection of the brake components, the rotors
are smooth, no grooves, and the pads have only worn
down about 10%. I am still getting a "chirping" or squeek,
which stops when the brakes are applied.
It appears that the pads are rattling loose within the
calipers and inadvertently contacting the rotor at speed,
and when the brakes are applied, the pads are squeezed
into flush contact with the rotor and the noise ceases.
After removal of the pads and shims, there appears to be
an adhesive like material on the back of the pads.
Is this suppose to keep the pads somewhat "adhered" to
the caliper piston, so that the pads do not make contact
with rotors after the brakes are released? If it does,
I am off to Autozone!
