Nope ... very likely an issue on the horizon back when you helped.
I believe/do in replacing vitals brake parts such as calipers and hoses, worth the often one time investment.

Really, she paid how much??? You need to call for pricing on rear goodies (calipers, any hoses and good pads) from a part store and tell her --- she needs someone to get her mad-on directed toward those thiefs, not you.

Good luck!
