Hi Bob -
If you have the original chrome plated Girling pots in there, little bits
of corrosion can start, causing the pot to stick a little. Worth taking
the right caliper off (it's easy) and taking the pots out looking for
rust. If that's the case, easy fix, replace the pots with SS replacements
and the seals, you'll never have a problem again.
Best Regards,
Alan

Your $0.02 is appreciated. Rotors and pads were replaced not too
long ago, but it's probably been 20 years since I rebuilt the
calipers.<br>
