One problem related to brake disc pads has been reported for the 1998 Ford F-250. The most recently reported issues are listed below.
When brakes are applied, brakes lock and release resulting in failure of vehicle to stop. When brakes are applied quickly, pedal goes to floor and brakes fail. When traveling over a bumpy surface, if brakes are applied, they fail. If driving on extremely wet roads and brakes are applied, they fail to work properly. Brakes pads and/or rotors have been replaced numerous times due to improper wear. Numerous attempts have been made with the dealer and Ford motor company to resolve.
