Brake adjustment
- Brake adjustment need can be seen from the brake tester
at the vehicle inspection centre and from the position of
the handbrake handle. When the handle points almost straight
up, the adjustment is correct.
There may still be differences between the wheels
even if the handle is positioned correctly
- Adjustment is simple: just tighten the wire. All brakes
are adjusted by pulling the rigging screw on the steel
bar behind the drawhead. When you turn the screw, the
entire bar becomes shorter or longer.
- As a rule of thumb, the adjustment is correct when the
handle points straight up.
- If wheels differ in terms of their brakes, you can adjust
them by turning the screws on the draw adjustment plate.
The screws are attached either to the outgoing wires or
steel bars.
- When the draw adjustment plates are roughly in a straight
angle with regard to the drawing bar, brake adjustment
is in balance.
Brake sensitivity can be separately adjusted
for each brake drum.
- When you have roughly adjusted the brakes from the rigging
screw and draw adjustment plates, you can fine-tune them
by tightening the 17 mm bolt in the brake plate and turning
the wheel at the same time until you feel the grip of
the brakes. Then one or two turns back (the same number
of turns for each wheel). The brakes have now been adjusted.
Note: All brake hubs nowadays have reversing
automatics so there is no need for separate latch locking. |
