8.13.(a).(ii): Linings thinner than the original equipment may result in contact with the wheel only across the middle and cause vibration during stops.

8.13.(b): Do no use re-lined shoes where the castings are damaged, worn or distorted.

8.13.(c): Square the brake to the wheel for optimum contact between the linings and the wheel.

8.13.(d): Type MST/E brakes utilize shoe clearance equalizing bolts to equalize brake shoe clearance; ensure that they are correctly adjusted in accordance with Chapter 6.

8.13.(e): Type MST/E brakes incorporate a mechanism to keep brake shoe clearance parallel to the wheel; ensure that it is correctly adjusted in accordance with Chapter 6.

8.14: Wheel run-out must be within the allowable tolerance; see Table 1. Any unnecessary lining drag will result in excessive heat in the wheel and lining deterioration.

8.15: Every operational test should include verification of brake wheel run-out as follows:

8.15.(a): At all speeds, verify that the linings are clear of the wheel. Take steps to correct wheel run-out, imbalance or the effects of critical speed.

8.15.(b): If necessary, check low speed brake wheel run-out as follows:

8.15.(c): Using a run-out gauge, verify that radial run-out does not exceed 0.001” per inch of brake wheel diameter. Refer to Table 1 for brake wheel run-out allowance. Bearing play can also be checked by lifting the brake wheel with a suitable lever while observing the dial gauge.
