Jim,
I've already replaced the caliper and got no change. None of the
mounting bolts look too long, the emergancy brake is used regularly and
is snug at about 4 clicks. The puzzle is that it occurs regularly after
a standard set of highway miles(10-12) and after an interval of 8-10 hrs
(parked during the day or overnight) is absent until the usual distance
is driven. When I replaced the rotors I was surprised at the difficulty
of removing the old versus the ease that this new one seems to almost
fall off the hub. I've attributed this to my failure to release the
parking in the initial replacement and have wondered if I damaged
something in the parking brake mechanism during the rotor removal. The
right side has behaved fine, but I do recall the rotor was easier to
remove. Whether I realized what was making the removal difficult or
merely a difference in the parking brake tightness, who knows. Thanks
for the help.
What you report is consistent with the e-brake shoe dragging against the
rotor when things heat up. Applying either the foot brake or the hand
brake will cause the noise to subside. Commonly happens if the holding
spring fails. REMOVE the rotor and examine the shoes and how they are
secured. Occasionally the friction material from the e-brake shoe will
spontaneously detach and grind away. Once in a while a small rock will
enter the e-brake housing and cause havoc.
