Service brakes
The service brakes are divided into two separate circuits. If a fault
arises in one of the circuits, the machine can still be braked with
the intact circuit.
If brake action is lost in both brake circuits, apply the exhaust brake
and the parking brake and stop the machine.
Parking brake
The parking brake should not be applied until the machine is
completely stationary.
Application and release, see page 49.
The parking brake is self adjusting (no after-adjustment is
necessary).
NOTE! When the parking brake is applied, it is not possible to
engage a gear.
Emergency brake
Q
In an emergency situation the parking brake may be used as an
emergency brake (if the parking brake is used as an
emergency brake, the load and dump brake will be engaged
automatically if the speed is above 2 km/h (1 mph)).
Q
The parking brake will be applied automatically, if the brake
pressure should be lost in both the front and rear circuits.
Engine retarding
Will be connected if:
– switch (A) is switched on, see also page 47.
– the accelerator pedal is fully released
– the engine speed exceeds 18.3 r/s (1100 rpm)
– the engine temperature exceeds 70 °C (158 °F).
Will be disconnected if:
– the accelerator pedal is pressed down
– the switch is switched off.
Load and dump brake
The load and dump brake activates the service brakes and puts
the transmission in neutral. This is to facilitate loading and
dumping.
This function can only be activated at speeds below 5 km/h (3.1
mph).
The function is deactivated when the gear selector is moved from
neutral position.
WARNING!
In case of a faulty brakes, stop the machine immediately
and contact a workshop authorised by Volvo CE for action
to be taken.
