Have an '04 Ranger FX4 Level II with 33,000 miles. During normal stopping condition I hear a squealing noise from the front brakes. When I do a hard stop the squealing disappears. I was wondering if anyone else had this problem and how to fix it. I have taken the brakes off and inspected and lubed the calipers but this did no good. Debating on trying new brake pads. Any recommendations?
