One problem related to brakes failed has been reported for the 2002 Ford F-250. The most recently reported issues are listed below.
Brake issue- have had disk's on the front surfaced once in 20k miles and is in need to resurface again. I have a 3/4 ton pickup, diesel and feel the rotors are not vented to reduce the (heat) build up sufficiently. I feel this is a engineering problem that should be remedied. Will wind up in brake failure.
