Wheel Removal (Cont.):
Removal of the wheels and brake drums revealed that water and blasting sand standing in the bottom of the drum had caused considerable corrrosion. Even after removal of this corrosion, the brake shoes were too tight to get the drums back on so an adjustment in the shoes of each wheel was made to create a gap betweeen brake and drum. It was noted that the leading edge of each brake shoe was champfered to prevent squeal when the brakes were applied. Silence was critical for undetected transport.
Note in the image at the bottom that the axles are at the ends of arms attached to a torsion bar. Note also the large adjustment nut to equalize or level the axles on the torsion bar.
