parking break 2011 Prius Squeaking Upon exit from vehicle

my 2011 gen3 chassis squeaks most times I get out of the vehicle with my parking break set. Doesn't do it when I do not apply the parking break.

Do you think it's as easy as pulling the tire and hitting it with break cleaner? I did the breaks my self last February. And, it was all fine up until around last September.

I appreciate any input.
