Motor bicycles first registered before I January
1927. must have a braking system which works on at least
one wheel.
Motor bicycles registered on or after 1 January 1927,
must have an efficient braking system with two means of operation
or two braking systems with separate means of operation.
Various locations may be used for braking controls.
Some motor bicycles have both braking systems operated from the
handlebars and some have linked where both wheels can be operated
from either control.
The vehicle presenter must be advised
of any defects found on an ABS system.

A.
1. Check that the motor bicycleis equipped with the appropriate
braking system or systems.
2. Check the condition and security of all controls and mountings.
3. Operate the brake pedal and lever fully several times and look
for:
a. wear at pivots
b. reserve travel
c. the position of the lever or pedal in relation to the foot rest
or handlebar
d. smoothness of operation
4. In the case of hydraulic systems, fully apply the control twice,
first slowly and then rapidly, each time to a point where sustained
pressure can be held and check for creep and sponginess.
5. Check components for corrosion, distortion and modifications
|
1. The motor bicycle does not have
the appropriate braking system or systems fitted according to its
age.
2.
a. An insecure brake control or mounting.
b. An Attachment screw loose or missing.
c. A fractured control lever or mounting.
3.
a. excessive wear at control lever pivots
b. inadequate reserve travel
c. a control which is inoperative or so damaged, positioned, bent
or shortened that the brake cannot be readily applied
d. a control which cannot be applied and released smoothly
4.
a. a hydraulic system control which creeps under load
b. sponginess indicating air in the hydraulic system.
5. deliberate modification which significantly reduces the original
strength of any component. Excessive corrosion, severe distortion,
a fracture or an inadequate repair to a component.
