129What braking system a motor vehicle must have

129 What braking system a motor vehicle must have independent brake, for a vehicle, means a brake that is operated entirely separately from any other brake on the vehicle, except for any drum, disc or part, on which a shoe, band or friction pad makes contact, that is common to 2 or more brakes. (2) A motor vehicle with 4 or more wheels built, or used, mainly for transporting goods or people by road must be fitted with: (a) a braking system that: (i) consists of brakes fitted to all wheels of the vehicle; and (ii) has at least 2 separate methods of activation, arranged so effective braking remains on at least 2 wheels if a method fails; or (b) 2 independent brakes, each of which, when in operation, acts directly on at least half the number of wheels of the vehicle. (3) The braking system of a motor vehicle mentioned in subrule (2) that was built after 1945 must have a service brake operating on all wheels that, when applied: (a) acts directly on the wheels and not through the vehicle’s transmission; or (b) acts on a shaft between a differential of the vehicle and a wheel. (4) The braking system of a motor vehicle with 4 or more wheels must have a parking brake that: (a) is held in the applied position by direct mechanical action without the intervention of an electrical, hydraulic or pneumatic device; and (b) is fitted with a locking device that can hold the brake in the applied position; and (c) has its own separate control. (5) The parking brake may also be the emergency brake.

Motor Vehicles (Standards) Regulations 2003 – Australian Vehicle Standards Rules 68 (6) If 2 or more independent brakes are fitted to a motor vehicle with 4 or more wheels, the brakes must be arranged so brakes are applied to all the wheels on at least 1 axle of the vehicle when any brake is operated. (7) A motor bike or motor trike must be fitted with: (a) 2 independent brakes; or (b) a single brake that acts directly on all wheels of the vehicle and is arranged so effective braking remains on at least 1 wheel if a part of the system fails. (8) Subrule (7) applies to a motor bike with a sidecar attached as if the sidecar were not attached. (9) A motor trike must have a parking brake that is held in the applied position by mechanical means.
