Western Australian Current Regulations Western Australian Current Regulations (1) In this
regulation —
independent brake , for a motor 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 subregulation (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) A motor
vehicle’s parking brake may also be its emergency brake.
(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 one axle of the vehicle when any brake is operated.
(7) A motor cycle or
motor tricycle 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 one wheel if a part of the system
fails.
(8)
Subregulation (7) applies to a motor cycle with a sidecar attached as if
the sidecar were not attached.
(9) A motor tricycle
must have a parking brake that is held in the applied position by mechanical
means.
