With properly adjusted brakes, complete braking of
both wheels should take place at the same time.
Brakes adjustment involves changing the position of
expander arm 1 (fig. 17) with respect to the expander roller 2.
To do this, remove the retaining ring 3 of roller 2, and then
remove arm 1 of shaft 2. Then move the expander arm on the
conjunction with the roller by one or more teeth in the right
direction, namely:
•
back - if the brake is too late;
•
forward - if the brake is too early.
Once the proper position of the arm 1 is achieved relative to
expander roller 2, you must tighten nut 4.
The adjustment should be conducted separately for
each trailer wheel. After proper brake adjustment, at full
braking, the expander arms should form an angle of 90
o
with
the piston rod of the actuator, and the spring should be about
half the length of the spring of the total piston rod. After
releasing the brake, the expander arms may not be based on
any structural elements, because too little withdrawal of the
piston rod can cause friction of the jaws against the drum and
result in overheating of the trailer brakes. The expander arms
arranged on one axis must be parallel to each other at full
braking. If not, adjust the position of the lever, which has a
longer spring. When removing, the actuator fork you must
remember or mark the original setting of the swivel of the
actuator fork. The mounting position is chosen by the
manufacturer and cannot be changed.
