ANNEXES

        Annex 1   - Communication concerning the approval or extension or refusal or withdrawal of approval or production definitely discontinued of a type of vehicle of category L with regard to braking pursuant to Regulation No. 78

         Annex 1 - Appendix  -  List of vehicle data for the purpose of Regulation No. 90 approvals

        Annex 2   - Arrangements of approval marks

        Annex 3   - Test conditions, procedures and performance requirements

       1. SCOPE

        This Regulation applies to vehicles of categories L. [4]

        These categories do not include:

        (a) Vehicles with a Vmax of < 25 km/h;

        (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, L5, L6 and L7:  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;
