Thanks Dennis. The rebuilds didn't look too expensive ($50 + $50 core
deposit) and would probably be much better than what I could do. I assume
you want to replace both sides to ensure equal braking.
Thanks for the info about the Girling changes.
I will try and clean this one out a bit, it had been sitting quite a but
this winter. I will order a replacement set as well, and it is probably a
good idea to replace the rubber hose while I'm at it.
