I think its brake pads
As mentioned only thing i can think for front is my pads rattling in callipers
well the last annoying noise i had from rear off truck was the parking brake so that was an easy fix, it just needed tightening up.Anything loose around the brakes? I've heard it could be parking brake but there isn't any of that going on in the front in to my knowledge. Mine is coming from drivers rear.
