Front brake squeak help

I just put alloy chromoly shafts in my Dana 30 which required pulling the brakes off of course.Now everything is back together and woks fine including stopping, but the brakes now squeak a little bit when I'm doing a slow rolling stop.Its not bad but still annoying.They were quiet before the axle shaft swap.Any ideas whats going on and what I can try to quiet them?Thanks!

Disk brake anti-squeal goop comes in a squeeze bottle. It has a consistency like toothpaste. You smear some on the contact surface on the BACK of the brake pad. Give it a few minutes to start to thicken, then install the pads. Allow the stuff to dry before driving. Works for me.
