pressure to the disk by the wear pattern on each side of the disk. If the wear
is even and the surfaces look very similar likely the pads are not seized. Don't
rule out air in the brake line. Are the flex hoses rubber or stainless steel
braid? You may have a flex hose that is expanding due to pressure in the brake
line.</FONT></SPAN></DIV>

<DIV>Maybe the right caliper was fluid starved for so long that is froze in
place or at least is binding up for that reason. If all the brake lines
are clear, the only thing left is the caliper. Sounds like time for a
rebuild. Just my two cents.</DIV>
