5-6 Disc Inspection
A new brake disc has a thickness of 5 mm, which
is indicated on the top of the brake. If excessive
brake wear is apparent or the air gap is
significantly greater than 0.012" (0.3mm),
measure the brake disc with a caliper. See Figure
521.
Maximum brake wear is 0.040" [1mm] - If disc
thickness is less than 4 mm, the brake disc must
be replaced.
5-7 Brake Air Gap Adjustment
If adjustment is required proceed as follows.
The air gap should be 0.012" [0.3mm]. If
necessary, adjust by means of the three set
screws and counter nuts as follows:
1) Loosen the three socket head fixing screws a
few turns as shown in Figure 522.
2) Adjust each of the three 8mm adjustment
screws (Figure 523) AN EQUAL # OF
DEGREES to either increase or decrease
the air gap (a) to 0.012" [0.3mm].
Unbalanced adjustments will lead to
excessive brake wear.
