Yes on both counts. Sticking pins are so common I suspect they are a major
cause of brake pad wear. I have been lucky enough to be able to clean and
relube all the pins I've encountered so far, but replacements are usually
inexpensive enough it might be a fool's errand to reuse them.
My wife's car is a Toyota Prius hybrid, and the brakes are used so lightly
(normally relies on regenerative braking above 11 mph except on rough
surfaces or hard stops) that I expect to relube them at least once before
time for pad replacement. A Prius tech in the Yahoo Prius group recommends
relubing every 30K miles. 50K should be okay for Volvos, I'd guess.
