Brake Adjustment

1. Check for brake link 2 13/16 inches (7.1 cm)
measurement as described in the Brake Link
Adjustment section.
2. Engage the brake lever (lever up). The space
between the brake spring bracket and the nyloc
nut under the spring should measure 1/8 inch to
3/16 inch (3.2–4.8 mm).
3. If adjustment is necessary, loosen jam nut above
the trunnion roller. Adjust the nyloc nut under
the trunnion roller until distance listed above
exists between the spring retainer bracket and the
adjacent nyloc nut. Tighten the jam nut above
the trunnion roller.
4. If the correct gap can no longer be achieved
because there is no clearance between the nyloc
nut below the spring and the jam nut above
the trunnion or there are no threads left on the
bottom nyloc nut, the length of the brake rod can
be adjusted. Remove a pin from a yoke at either
end of the brake rod and lengthen (or shorten) the
brake rod until the correct gap can be achieved by
following steps 2 and 3.
