proper braking.
1. Insert a 0.015–0.021 inch (0.381–0.533 mm) feeler

assembly. Make sure it is between the armature and
the rotor friction surfaces.
2. Tighten the lock nuts until there is slight binding on
the feeler gauge but it can be moved easily within the
air gap (Figure 40).
3. Repeat this for the remaining slots.
