Is threadlock needed on our caliper bolts?

I did a brake job about a month ago with no problems so far.
Noticed the caliper bolts were previously applied with blue threadlock.
Did not have any threadlock (thought I did) and chose move on without reapplying.
Just used a torque wrench and applied 80-90lb.
Any opinions on whether it is truly needed, or if the previous application would work.

Thanks
