with soft jaws. Unscrew the upper self-adjust screws
(Figure 8-66) and remove the springs and bushings.

Remove the piston out from the front of the brake flange.
If necessary, use compressed air through the bleed
screw port to eject the piston. The piston may eject with
force, be sure no part of your body or other persons are
in the way of the ejecting piston.
11. Remove the quad rings (Figure 8-68) from the piston
and check their condition.

screw (Figure 8-69). Using SPECIAL TOOL P/N

CAUTION
This procedure frees the differential housing, which could
fall if not properly supported causing possible personal
injury.
CAUTION
When using compressed air to remove the piston,
pressure is created behind the piston resulting in possible
forcible ejection of the piston. Keep clear of the front of the
brake flange. Possible personal injury could result from
the ejected piston.
