Campaign:

74V030000 on 10/11/1979

Component:

Service brakes, hydraulic:power assist:vacuum

Affected:

5,717

Notes:

Checker campaign no n/a.possibility that the single diaphragm brake vacuumpower booster was assembled with dimensional discrepancies in the vacuum powerbooster housing which may reduce the torque required to unlock the front halfof the housing from the rear half.if this condition exists, the low unlockingtorque coupled with other variations in the assembly may cause housing torotate and disengage from the locking tabs resulting in separation of the twohalves of the booster and complete loss of brakes.(correct by inspecting andstaking the housing at two points to preclude rotation of the housing).
