Instruction manual

2) Inspect the inside of the fan cover for
excessive brake dust (Figure 507). This
indicates brake wear caused by an
incorrectly adjusted brake or possibly low
voltage usage. It may also be an indication of
excessive EMERGENCY DESCENT usage.
3) Measure the clearance (a) between the
pressure plate and the black brake body with
a feeler gauge. This should be done in all
three places between the 3 fixing screws
every 120 degrees (Figure 508).
4) Measurement of the air gap (a) should be
0.012"(0. 3mm) (Figure 509 and Figure 510).
If the air gap (a) needs an adjustment, refer
to Section 5.6.
