Firsts thing in the morning,when i start moving.The right frt wheel locks up,even if i haven't touched the brakes.I step on the brakes & a pop is felt n the body of the truck.Then it will move a couple of feet & then lock up again.Must step on the brake again & pop felt then it is fine all day.Or unless the vehicle sits for a couple of hours.
Both front brake calipers & hoses have been replaced & mastercylinder.Brakes have been bled numerous times.

Call me crazy but are wheel lugs torqued down? Rotor seated on hub?
