My Sienna CE and have had an on going
problem with the rear brake drums. The
rear brakes have a thumping sound under
low speed braking. There is little
point to machine the rear brake drums,
since this remedy does not work. Toyota
has not been able to repair the rear
brakes because of “hot spots or hard
spots” in the drums. The turning of
the drums is only a temporary solution
and has the brake wear the “harden
spots” become high spots that cause the
thumping noise to occur.
