If the brake feels fine, check the hub for damage. It should be the cam lock style hubs and they cannot be shifted into 4x4 unless stopped. If they don't unlock, they probably need to be serviced or replaced. If the brake feels funny, check the wheel bearings to see if they have excessive lateral movement causing the hub not to disengage. If both areas are ok, you might have front axle damage. The front axle only engages in 4x4 mode.
