Notes

Jeep campaign no lampwir.trucks with power brakes.possibility that thebrake vacuum power booster was assembled with dimensional discrepancies in thevacuum power booster housing which may reduce the torque required to unlock thefront half of the housing from the rear half.if this condition exists, thelow unlocking torque coupled with other variations in the assembly may causehousing to rotate and disengage from the locking tabs resulting in separationof the two halves of the booster and complete loss of brakes.(correct byinspecting and staking the housing at two points to preclude rotation of thehousing).
