3.                                          DEFINITIONS

3.1.                                    For vehicle categories, definitions and meanings used in this standard, refer to Vehicle Standard (Australian Design Rule Definitions and Vehicle Categories) 2005.

4.                                          DESIGN REQUIREMENTS

4.1.                                    'Service Brake System'

4.1.1.                              The vehicle must be equipped with a 'Service Brake System' operable on all road wheels through the medium of a single 'Control' so placed that it can be actuated by the operator from the normal driving position.

4.1.2.                              The vehicle must have one or more service brake failure 'Visible Indicators' meeting the requirements of clause 4.2.

4.1.3.                              Where separate methods of actuation are provided for any of the functions of the brake system, the actuation of one function must not cause the operation of another function.

4.1.4.                              Each 'Service Brake System' must incorporate devices which compensate for any increased movement of its components arising from wear.  Such devices must themselves contain provision for securing them throughout their working range in any position to which they may be adjusted to or to which they may themselves automatically adjust.

4.1.5.                              Where a vehicle is equipped with an 'Antilock System' it must meet the requirements of APPENDIX 1.

4.1.6.                              All components and devices in the 'Brake System' must meet or exceed at least one appropriate and recognized international, national or association standard, where such standards exist, or the relevant parts thereof.  'Recognized' can be taken to include SA, SAE, BS, JIS, DIN, ISO and ECE standards.

4.1.7.                              Traction control systems may utilize part of the 'Service Brake System' provided that, except for parts common to both the traction control system and the 'Service Brake System', the traction control system or any failure of it can not interfere with normal braking.

4.1.8.                              Brake line couplings must not be interchangeable and must be polarized.  Couplings must comply with the requirements of AS 4945-2000 Commercial road
