35.1.2.                          'Audible Indicator' - a device incorporated in a 'Brake Power Unit 35/00' system which indicates to the operator by an intermittent or continuous audible signal that the supply pressure of the working fluid in the system has fallen below a predetermined level.
35.1.3.                          Not used.
35.1.4.                          'Average Operating Pressure' - the arithmetic average of the 'Manufacturer's' specified maximum and minimum pressures in the operating pressure range.
35.1.5.                          Not used.
35.1.6.                          'Brake Power Unit 35/00' - a device installed in a brake system that stores the energy required to actuate the brakes and provides the energy either directly or indirectly through an auxiliary device, with the operator
action consisting only of modulating the energy application level.
35.1.7.                          Not used.
35.1.8.                          Not used.

35.1.11.                      'Initial Brake Control Location' - the location of the brake 'Control' within the first 3 mm of travel of the centre of the brake pedal pad.
35.1.12.                      'Lightly Loaded Test Mass 35/00' - the mass of the unladen vehicle with a full capacity of lubricating oil and coolant and not less than 75 per cent of full fuel capacity, but without goods, occupants or options except those options which are essential for the test procedures specified, plus additional loading distributed in the seating position adjacent to the driver's seating position so that the mass of such loading plus the mass of the driver and instrumentation mounted in the vehicle is 155 ± 30 kg. In the case of a vehicle in "cab-and-chassis" condition an additional load not exceeding 7.5 per cent of the 'GVM' shall be located with its centre of mass within 200 mm of the 'Manufacturer's' designated load centre, measured in a horizontal plane.
35.1.13.                      'Lock Actuator' - a device which ensures braking operating of the parking brake by mechanically locking the brake piston rod.
35.1.14.                      'Maximum Laden Vehicle Speed' - the speed attainable at 1.6 km from a standing start under maximum acceleration with the vehicle at 'Maximum Loaded Test Mass', established by either test or calculation.
35.1.15.                      'Maximum Loaded Test Mass 35/00' - the mass of the laden vehicle loaded to 'GVM' rating with the load so distributed over the load bearing area of the vehicle as not to exceed the 'Manufacturer's' nominated individual 'Axle Loads'.
35.1.16.                      'Parking Brake System 35/00' - a system that, through the medium of a 'Control' independent of the service brake 'Control', applies a restraining force to 2 or more road wheels of the vehicle to either
