2.2.6.

2.2.8.
The tyre dimensions.
2.3.
‘Braking equipment’ means the combination of parts whose function is progressively to reduce the speed of a moving vehicle or bring it to a halt, or to keep it stationary if it is already halted; these functions are specified in paragraph 5.1.2. below.
The equipment consists of the control, the transmission, and the brake proper.
2.4.
‘Control’ means the part actuated directly by the driver to furnish to the transmission the energy required for braking or controlling it.
This energy may be the muscular energy of the driver, or energy from another source controlled by the driver, or a combination of these various kinds of energy.
2.5.
‘Transmission’ means the combination of components comprised between the control and the brake and linking them functionally.
The transmission may be mechanical, hydraulic, pneumatic, electric or mixed.
Where the braking power is derived from or assisted by a source of energy independent of the driver, the reserve of energy in the system is likewise part of the transmission.
The transmission is divided into two independent functions: the control transmission and the energy transmission.
Whenever the term ‘transmission’ is used alone in this Regulation, it means both the ‘control transmission’ and the ‘energy transmission’:
2.5.1.
‘Control transmission’ means the combination of the components of the transmission which control the operation of the brakes, including the control function and the necessary reserve(s) of energy;
2.5.2.
‘Energy transmission’ means the combination of the components which supply to the brakes the necessary energy for their function, including the reserve(s) of energy necessary for the operation of the brakes.
2.6.
‘Brake’ means the part in which the forces opposing the movement of the vehicle develop.
It may be a friction brake (when the forces are generated by friction between two parts of the vehicle moving relatively to one another); an electrical brake (when the forces are generated by electro-magnetic action between two parts of the vehicle moving relatively to but not in contact with one another); a fluid brake (when the forces are generated by the action of a fluid situated between two parts of the vehicle moving relatively to one another); or an engine brake (when the forces are derived from an artificial increase in the braking action, transmitted to the wheels, of the engine).
2.7.
‘Different types of braking equipment’ means equipment which differ in such essential respects as:
2.7.1.
Components having different characteristics;
2.7.2.
A component made of materials having different characteristics, or a component differing in shape or size;
2.7.3.
A different assembly of the components.
2.8.
‘Component of the braking equipment’ means one of the individual parts which, when assembled, constitutes the braking equipment.
2.9.
‘Progressive and graduated braking’ means braking during which, within the normal operating range of the device, and during actuation of the brakes (see paragraph 2.16. below):
2.9.1.
The driver can at any moment increase or decrease the braking force by acting on the control;
2.9.2.
The braking force varies proportionally as the action on the control (monotonic function);
2.9.3.
The braking force can be easily regulated with sufficient precision.
