3.24 CHECKING THE BRAKE CYLINDER FASTENING
1.
Check that the brake cylinders do not move
during operation of the service brake.
3.25 INSPECTION, BRAKE LINING THICKNESS
1.
Pressurise the air brake system (pressure
regulator should cut out) and make sure that
the vehicle's parking brake is not activated.
2.
Check the brake lining thickness through the
openings in the dust cover.
3.
Replace the brake lining if it is worn down to
the wear indicator mark on the lining.
Note:
If in doubt about the amount of brake lining
wear, release the brakes and remove the
dust cover.

Check whether guide bush (4) protrudes
from guide sleeve (6) (C).
If the guide bush (4) is level with the guide
sleeve (6) (see detail A) the brake shoe and
brake disc thicknesses should be checked.

3.27 CHECKING AND ADJUSTING LOAD-SENSING AIR-SUSPENSION CONTROL
VALVE
Explanatory notes on instruction plate
This plate is mounted on the rear door pillar on
the left-hand side of the vehicle. The information
on the instruction plate relates to the axle loads,
the delivery pressures and bellows pressures,
following the sequence of the axles beneath the
vehicle.
Therefore, "1" refers to the (first) front axle, "2" to
the next following axle, etc.
If the vehicle is fitted with a relay valve in the front
axle brake circuit, the box beneath the valve
illustration will be blank. Throughout the column,
a value of 8.1 bar has been filled in for "delivery
pressure p2" under axle "1".
If the vehicle is equipped with a control valve
instead of the relay valve mentioned, the box will
contain a pressure ratio, e.g."i = 1 : 1.5". The
"delivery pressure p2" of axle "1" then indicates
variable readings.
These values can be used to check the brake
pressure values of the front axle and to carry out
the inspection/adjustment below at the same
time. To do this, connect a pressure gauge to the
test connection of one of the front axle brake
cylinders.
