should be roughly 1 1/2” between the head of
the shoulder nut and the brake bracket when the
brakes are applied.
7.23. Tighten the jam nut.
7.24. If brake application is uneven from left to right,
adjust the length of the short connector rods
between the brake bracket and the brake bear-
ing hub.
7.25. If brake release action is inconsistent, check for
bent or misaligned rods and links.
7.26. Install the rear wheels, tightening the lug nuts to
50-70 ft.-lbs. Lower the TANK to the ground.
7.27. Install the floor panel.
7.28. Test run the TANK in a safe area before return-
ing it to service. Check the function of the park-
ing brakes.
NOTE: A dragging parking brake will cause
tracking issue and drive noise on the effected
side.
