My 1999 F150 has squeaky front brakes when applying brakes at idling speeds. My truck has 103000 miles. I have replaced front pads twice in the last 6 months(ceramic pads), and are wearing normally. I replaced the rotors approx 30000 miles ago. When applying the brakes at speeds of 15-20 miles per hour or over, the brakes perform normally quiet. They have never squeaked until now.

 

No miracles from this guy, some do and some don't. Change pads and rotors and can still squeak. Heat, hardness, glazing, all contribute.

 

Try some of the anti squeaky products found at the parts store.
