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.
