To make this adjustment release the lever from the brake
actuator, slacken the clamp bolt and remove the lever from
the cam shaft spline. Turn the lever 1 or more teeth of the
spline towards the actuator. The cam shaft may need to be
rotated in the opposite direction to align the splines. Slide
the lever back onto the shaft.
Reconnect the brake lever to the brake actuator and make
sure that the brake shoes are not in contact with the drum,
and the wheel can rotate freely.
IMPORTANT: The pivot point of the actuator on the lever
must not be altered without the permission of the vehicle
manufacturer because this will change the braking
efficiency of the vehicle. The factory set position is listed in
the table below.
Table 10. Brake actuator position on brake lever.
13.22.2 Adjusting Brake Levers
-
Adjustable lever.
Safely raise the vehicle as described in section 13.14.
Adjust the position of the lever by rotating the screw
clockwise when the brakes are not applied (Figure 19).
Adjust the lever to the closest possible setting that still
allows the wheel to turn freely. Apply grease to the lever
using the grease nipple provided.

13.23 Pneumatic Brakes
The two
-
line trailer braking system which is fitted to this
machine uses one Red air line (known as a supply or
emergency line) which, when coupled to the tractor is
permanently pressurised, and one Yellow line (known as
the service or control line) which has a variable pressure.
This variable pressure is controlled by the tractor, and is
determined by the force on the brake pedal or whether
the tractor’s parking brake is applied.
It is commonplace for this line to be fully pressurised
when the tractors ignition is switched OFF.
13.23.1 Connector Filters
The air enters the trailer via the red and yellow flexible
connection lines, and passes through a filter in each line.
The filters are designed to trap particles of dirt, and to stop
them entering the system, they are not designed to stop
water entering the system.
Filters should be dismantled and cleaned from time to
time to remove any debris.
13.23.2 Air reservoir
To remove any water that has condensed in the air
reservoir it should be drained daily.
A drain valve is fitted at the bottom of each air reservoir.
13.23.3 Trailer control valve
The trailer control valve has several functions, one of which
is load sensing.
CAUTION: The Tomahawk has 3 pre
-
set brake
settings (laden, part laden and empty) as the machine
does not have suspension. The linkage is pre
-
set to give
the correct brake performance and should not be adjusted.
Oil the pivot points.
13.23.4 Air lines
Inspect regularly for leaks.
13.24 Lubrication
Good quality semi
-
solid grease should be applied to the
grease points as shown on the relevant lubrication chart on
pages 2 to 5.
The frequencies stated are based on typical daily use for
bedding & feeding purposes. Continuous use for special
applications will necessitate more frequent lubrication.
