3.1 Brake Controls
|Information||Method of Inspection||Reason for rejection|
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.
1. Check that the machine is equipped with the appropriate braking system or systems. (see information column)
2. Check the condition and security of the foot pedal and handlebar brake lever and mountings.
(see information column)
3. Operate the brake pedal and lever fully several times and look for:
b. wear at pivots
c. reserve travel
d. the position of the lever or pedal in relation to the foot rest or handlebar
e. 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
The machine does not have the appropriate braking system or
systems fitted according to its age.
2. An insecure brake control or mounting. Attachment screws loose or missing. A cracked control lever or mounting.
a. an insecure control
b. excessive wear at control lever pivots
c. inadequate reserve travel
d. a control which is inoperative or so damaged, positioned, bent or shortened that the brake cannot be readily applied
e. a control which cannot be applied and released smoothly
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.
