H . Bleeding the trailer brake circuit
If the tractor is fitted with an FTE valve (14) (Fig. 17), it
is strongly recommended to simultaneously bleed the
main brake and trailer brake circuits.
To carry out this bleeding procedure, use the same
equipment and methods as described in paragraph G
for the bleeding of the main brake circuit while
complying with the following additional points:
• Open (Fig. 18):
- the two screws (1) of the main brakes;
- the trailer brake screw (2).
• When the bleeding is complete, tighten in the
following order
(Fig. 18):
- the left-hand brake bleed screw (1);
- the right-hand brake bleed screw (1);
- the trailer brake bleed screw (2).
• Check the trailer braking pressure on the quick
disconnect coupling located at the rear of the tractor
(see chapter 9).
If this pressure is not correct, eliminate any air leaks
in the circuit and repeat the bleeding procedure.
• Carry out a road test.
