Step 6
Check the unladen setting by applying the test pressure down the yellow line (6.0 bar used in this example) and
measure the RELSV output pressure.
This can be measured directly at any unused port 2, or on a brake chamber.
If the pressure is correct (2.5 bar in this example), then the valve is now set up.
If the pressure is too low (2.0 bar for example), then the vertical linkage between the RELSV arm and the axle (or bar)
is too short.
Conversely, if the output pressure is too high, then the vertical linkage is too long.
Amend the length until the unladen output pressure is correct (tolerance ± 0.2 bar).
Having set the RELSV at its correct unladen setting, and adjusted the arm length to match
the true unladen/laden spring deflections, the valve should now automatically adjust to the correct brake pressure
settings.
6.3.7 SAFE COUPLING AND UNCOUPLING OF TRACTOR/TRAILERS WITH TWO-LINE AIR
BRAKING
The safe operation of the two-line air system relies on the driver correctly connecting the two air lines between the
tractor and trailer, as well as any ABS power cable.
When coupling an air braked trailer to a tractor never have just the red line connected. (That is to say, connect the
yellow line first when coupling, and remove the red line first when uncoupling.)
Follow all other Health & Safety rules and remember it is always good practice to not walk/climb between the tractor
and trailer during coupling and uncoupling.
6.3.8 SPRING PARKING BRAKES
6.3.8.1 INTRODUCTION
Spring brakes are designed to work when you are parking your trailer or in an emergency when your service brakes
fail. This chapter explains the operation and function of the spring brakes subsystem.
