ok, grammar police...CALIPER CALIPER....P not B

now that I got that out of my system...yes, I'd go with a new/reman vs. used...

if it's the same side with the used caliPER, I'd look to see if there's a swollen brake hose to it, that can cause calPERS to stick...also make sure the drum-in-hat parking brake isn't hanging up...
