NHTSA Campaign Id 79V201000; Date: Nov. 2, 1979
1979 Ford F250
Component: Service Brakes, Hydraulic:foundation Components:disc:rotor
Manufactured by: Ford Motor Company
Affected Units:: 500
Dimensional differences in the 1980 versus the 1979 assemblies may allow the inner brake lining/shoe to move outward to a position where it is no longer retained in the shoe slot when the front brake inner linings become worn to the point of needing replacement. The inner brake shoe could then wedge between the rotor and spindle, possibly causing a sudden lock-up of one front wheel. This can occur without brake application and would adversely affect steering control. These dimensional differences could also allow additional travel of the brake piston such that a loss of brake fluid from the front brake system may occur. This would result in increased stopping distances.
The dealer will inspect and, if necessary, replace the hub and rotor assemblies and spindle seals.
Vehicle description: light trucks with 6200 and 6900 lb gvwr and equipped withtwo wheel drive and standard front brakes. System: service brakes; brake assembly. Consequences of defect: loss of steering control along with increased stoppingdistances could result in an accident.
