either two separate service brake systems, or a split service brake system, with at least one brake operating on the front wheel and at least one brake operating on the rear wheel.

       5.1.6. Three-wheeled vehicles of vehicles category L4 shall comply with the brake system requirements set out in paragraph 5.1.5.  A brake on the sidecar wheel is not required if the vehicle meets the performance requirements prescribed in Annex 3, paragraph 4.

       5.1.7. Three-wheeled vehicles of category L2 shall be equipped with a parking brake system plus one of the following service brake systems:

            (a) Two separate service brake systems, except CBS, which, when applied together, operate the brakes on all wheels; or

            (b) A split service brake system; or

            (c) A CBS that operates the brakes on all wheels and a secondary brake system which may be the parking brake system.

       5.1.8. Category L5 vehicles shall be equipped with:

       5.1.8.1. A parking brake system; and

       5.1.8.2. A foot-actuated service brake system which operates on the brakes on all wheels, by way of either:

            (a) A split service brake system; or

            (b) A CBS that operates the brakes on all wheels and a secondary brake system, which may be the parking brake system.

       5.1.9. In cases where two separate service brake systems are installed, the systems may share a common brake, if a failure in one system does not affect the performance of the other.

       5.1.10. For vehicles that use hydraulic fluid for brake force transmission, the master cylinder shall:

           (a)           Have a sealed, covered, separate reservoir for each brake system;

           (b)          Have a minimum reservoir capacity equivalent to 1.5 times the total fluid displacement required to satisfy the new to fully worn lining condition with the worst case brake adjustment condition; and

            (c) Have a reservoir where the fluid level is visible for checking without removal of the cover.

       5.1.11. All warning lamps shall be mounted in the rider's view.

       5.1.12. Vehicles that are equipped with a split service brake system shall be fitted with a red warning lamp, which shall be activated:

            (a) When there is a hydraulic failure on the application of a force of ≤ 90 N on the control; or

            (b) Without actuation of the brake control, when the brake fluid level in the master cylinder reservoir falls below the greater of:

               (i)            That which is specified by the manufacturer; and

             (ii) That which is less than or equal to half of the fluid reservoir capacity.

        To permit function checking, the warning lamp shall be illuminated by the activation of the ignition switch and shall be extinguished when the check has been completed.  The warning lamp shall remain on while a failure condition exists
