Figure 7-33. Measuring Brake Air Gap

Brake Air Gap Adjustment

During normal use, the friction plate will wear
(get thinner). This causes the air gap to
increase.
With the brake energized, measure the total air
gap with a feeler gauge. The total air gap should
be 0.010 to 0.015 inch (0.25
uniform all the way around the armature disc.
A total gap greater than 0.015 inch (0.38 mm)
indicates brake wear.
If the air gap is too large, the brake may not
work properly; this is especially true when the
brake is hot or the battery charge level is low.
