                   (b)     Vehicles equipped for disabled riders.
 
2.                DEFINITIONS
 
                   For the purposes of this Regulation:
 
2.1.             "Antilock brake system (ABS)" means a system which senses wheel slip and automatically modulates the pressure producing the braking forces at the wheel(s) to limit the degree of wheel slip.
 
2.2.             "Approval of a vehicle" means the approval of a vehicle type with regard to braking.
 
2.3.             "Baseline test" means a stop or a series of stops carried out in order to confirm the performance of the brake prior to subjecting it to a further test such as the heating procedure or wet brake stop.
 
2.4.             "Brake" means those parts of the brake system where the forces opposing the movement of the vehicle are developed.
 
2.5.             "Brake system" means the combination of parts consisting of the control, transmission, and brake, but excluding the engine, whose function it is to progressively reduce the speed of a moving vehicle, bring it to a halt, and keep it stationary when halted.
 
2.6.             "Combined brake system (CBS)" means:
 
                   For vehicle categories L1 and L3:  a service brake system where at least two brakes on different wheels are operated by the actuation of a single control.
 
                   For vehicle categories L2 and L5:  a service brake system where the brakes on all wheels are operated by the actuation of a single control.
 
                   For vehicle category L4:  a service brake system where the brakes on at least the front and rear wheels are operated by the actuation of a single control.  (If the rear wheel and sidecar wheel are braked by the same brake system, this is regarded as the rear brake.)
 
2.7.             "Components of the braking system" means one of the individual parts which, when assembled, constitute the braking system.
 
2.8.             "Control" means the part actuated directly by the rider in order to supply or control the energy required for braking the vehicle to the transmission.
 
2.9.             "Different types of braking systems" means devices which differ in such essential respects as:
 
                   (a)     Components having different characteristics;
 
                   (b)     A component made of materials having different characteristics, or a component differing in shape or size;
 
                   (c)     A different assembly of the components.
 
2.10.           "Driver mass" means the nominal mass of a driver that shall be 75 kg (subdivided into 68 kg occupant mass at the seat and 7 kg luggage mass).

2.16.           "Mass in running order" means the sum of the unladen vehicle mass and driver mass.
 
2.17.           "Peak braking coefficient (PBC)" means the measure of tyre to road surface friction based on the maximum deceleration of a rolling tyre.
 
2.18.           "Power-assisted braking system" means a brake system in which the energy necessary to produce the braking force is supplied by the physical effort of the rider assisted by one or more energy supplying devices, for example vacuum assisted (with vacuum booster).
 
2.19.           "Secondary brake system" means the second service brake system on a vehicle equipped with a combined brake system.
 
2.20.           "Service brake system" means a brake system which is used for slowing the vehicle when in motion.
 
2.21.           "Single brake system" means a brake system which acts on only one axle.
 
2.22.           "Split service brake system (SSBS)" means a brake system that operates the brakes on all wheels, consisting of two or more subsystems actuated by a single control designed so that a single failure in any subsystem (such as a leakage type failure of a hydraulic subsystem) does not impair the operation of any other subsystem.
 
2.23.          "Stopping distance" means the distance travelled by the vehicle from the point the rider begins to actuate the brake control to the point at which the vehicle reaches a full stop.  For tests where the simultaneous actuation of two controls is specified, the distance travelled is taken from the point the first control is actuated.
 
2.24.          "Test speed" means the vehicle speed measured the moment the driver begins to actuate the brake control(s).  For tests where the simultaneous actuation of two controls is specified, the vehicle speed is taken from the point the first control is actuated.
 
2.25.           "Transmission" means the combination of components that provide the functional link between the control and the brake.
 
2.26.           "Unladen vehicle mass" means the nominal mass of the vehicle as indicated by the manufacturer(s) including all factory fitted equipment for normal operation of that vehicle (e.g. fire extinguisher, tools, spare wheel), plus coolant, oils, 90 per cent of fuel and 100 per cent of other gas or liquids, as specified by the manufacturer.

                   (i)      The final drive ratios;
 
                   (j)      The tyre dimensions.
 
2.28.           "Vmax" means either the speed attainable by accelerating at a maximum rate from a standing start for a distance of 1.6 km on a level surface, with the vehicle lightly loaded, or the speed measured in accordance with ISO 7117:1995.
 
2.29.           "Wheel lock" means the condition that occurs when there is a slip ratio of 1.00.
 
3.                APPLICATION FOR APPROVAL
 
3.1.             The application for approval of a vehicle type with regard to braking shall be submitted by the vehicle manufacturer or by his duly accredited representative.

5.2.             Durability
 
5.2.1.          Wear of the brakes shall be compensated for by means of a system of automatic or manual adjustment.
 
5.2.2.          The friction material thickness shall either be visible without disassembly, or where the friction material is not visible, wear shall be assessed by means of a device designed for that purpose.
 
5.2.3.          During all the tests in this Regulation and on their completion, there shall be no friction material detachment and no leakage of brake fluid.
 
5.3.             Measurement of dynamic performance
 
                   The method used to measure performance is as specified in the respective tests in Annex 3.  There are three ways in which the service brake system performance may be measured:
 
5.3.1.          MFDD (Mean Fully Developed Deceleration):
 
                   Calculation of MFDD:
 

in m/s2
                   where:
dm = mean fully developed deceleration
V1 = vehicle speed when rider actuates the control
Vb = vehicle speed at 0.8 V1 in km/h
Ve = vehicle speed at 0.1 V1 in km/h
Sb = distance travelled between V1 and Vb in metres
Se = distance travelled between V1 and Ve in metres
 
5.3.2.          Stopping distance:
 
                   Based on the basic equations of motion:
 
                            S = 0.1·V + (X) ·V2
 
                   where:
                  
                            S = stopping distance in metres
                            V = vehicle speed in km/h
                            X = a variable based on the requirement for each test
 
                   To calculate the corrected stopping distance using the actual vehicle test speed, the following formula is used:
 
                            Ss = 0.1·Vs + (Sa – 0.1·Va) · Vs2/Va2
 
                   where:
                  
                            Ss = corrected stopping distance in metres
                            Vs = specified vehicle test speed in km/h
                            Sa = actual stopping distance in metres
                            Va = actual vehicle test speed in km/h
 
                   Note:  This equation is only valid when the actual test speed (Va) is within ± 5 km/h of the specified test speed (Vs).
 
5.3.3.          Continuous deceleration recording:
 
                   For the burnishing procedure and tests such as the wet brake and heat fade – heating procedure, there is a continuous recording of the vehicle's instantaneous deceleration from the moment a force is applied to the end of the stop.
 
5.4.             Brake lining materials:
 
                   Brake linings shall not contain asbestos.
 
6.                TESTS
 
                   The braking tests (test conditions and procedures) which vehicles submitted for approval are required to undergo, and the braking performance required, are prescribed in Annex 3 to this Regulation.
 
7.                MODIFICATIONS OF VEHICLE TYPE OR BRAKING SYSTEM AND EXTENSION OF APPROVAL
 
7.1.             Every modification of the vehicle type or of its braking system shall be communicated to the Administrative Department which approved the vehicle type.  That department may then either:
 
7.1.1.          Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the vehicle still complies with the requirements; or
 
7.1.2.          Require a further test report from the Technical Service responsible for conducting the tests.
 
7.2.             Confirmation or refusal of approval, specifying the alterations, shall be communicated, by the procedure specified in paragraph 4.3., to the Parties to the Agreement which apply this Regulation.
 
7.3.             The Competent Authority issuing the extension of approval shall assign a series number to each communication form drawn up for such an extension.
 
8.                CONFORMITY OF PRODUCTION
 
8.1.             Every vehicle (system) approved to this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraph 5.
 
8.2.             In order to verify that the requirements of paragraph 8.1. are met, suitable controls of the production shall be carried out.
 
8.3.             The holder of the approval shall in particular:
