The plane which is defined by the head-to-foot and anterior-to-posterior directions in the human body. A stack of images acquired in the sagittal plane separates images by their left-to-right locations. The mid-line sagittal plane bisects the left and right half of the human body.
Under heavy braking, the rear tires lock up and the axle begins to bounce; the amplitude of the bounce becomes so severe that the tires finally develop enough traction (when slamming hard against the pavement) to rip the whole axle assembly free of the vehicle.
If it has/will break or you think it will break, do not drive it. If it happens to break while you are on the road you will almost have no control of your vehicle. The wheel may decide to go left or right on its own,the best priority is to stay calm and do NOT slam on the breaks,this could lead to the car to lose control or even possibly roll.
