Releasing The Parking Brake With Inoperative Pneumatic System - Scania L Series Product Information

Recovery and shunting
Releasing the parking brake with inoperative
pneumatic system
If the compressed air system is deactivated, the parking brake can be released
by refilling with air from one of the tyres or from another pneumatic system.
Air can be filled using the pressurising hose, which can be found in the tool
equipment.
Connect the hose to one of the tyres and to the filler valve 28 or X904 on the
instrument cluster. This enables the parking brake to be released for a short
period of time.
WARNING!
Do not tow the vehicle with the parking brake released with refilled air for
long stretches because the brake will be applied if the air pressure drops.
The pressure indicator on the instrument cluster does not show the pressure
in the parking brake circuit.
Position on bus.
