(2) Visually inspect all parts for excessive
wear, burs, stripped threads, or other damage. Inspect
push-pull controls for freedom of movement.
(3) Repair by replacing defective components
or mounting hardware.
c. Swing Brake Linkage Adjustment.
(1) Refer to figure 3-103, adjust locknuts on
either side of point A so that lever touches edge of slot
in the side stand.
(2) Lay a straight edge from point A to point
B. Point C should be 5/8 inch nearer brake drum. This
will keep linkage from "toggling in". When toggling in
does occur, the brake will not release when pressure on
hydraulic cylinder is released.
(3) Adjust two locknuts so that alinement of
points A, B, and C are maintained as described in (1)
and (2) above.
(4) Adjust two locknuts on eyebolt at brake
release spring until there is just enough tension on
spring to release brake when hydraulic pressure is
released.
