          1. DESIGN REQUIREMENTS

1.1                                      Service Brake System

1.1.1                                The vehicle must be equipped with either a 'Split Service Brake System' or independently actuated service brake systems.  Vehicles which have independently actuated service brake systems must have 2 independent brake systems, one capable of acting on the front wheel and the other on the rear wheel(s).

1.1.2                                Failure of any component in a mechanical service brake system must not result in a loss of braking ability in the other service brake system.

1.1.3                                A leakage type failure in a hydraulic service brake system must not result in a loss of braking ability in the other service brake system.  Each vehicle equipped with a 'Hydraulic Brake System' must meet the requirements of clause 1.5.

1.1.4                                The service brake system must be installed so that the lining thickness of drum brake shoes may be visually inspected, either directly or by the use of a mirror without removing the drums, and so that disc brake friction lining thickness may be visually inspected without removing the pads.

1.1.5                                Except where the requirements of clauses 1.2. and 4.13 apply, a Category LD vehicle is only required to meet the requirements of this rule with the side-car detached.

1.1.6                                The 'Controls' by which brakes are actuated must be located so that they are readily accessible to the driver in the normal driving position.

1.1.7                                The service brake system must incorporate devices which compensate for any increased movement of its components arising from wear.  Such devices must themselves contain provision for securing them throughout their working range in any position in which they may be adjusted to or to which they may themselves automatically adjust.

1.1.8                                Where separate methods of actuation are provided for any of the functions of the brake system, the actuation of one function must not cause the operation of another function.

1.2                                      Parking Brake System for LB, LD and LE Vehicles Only

         The vehicle must be equipped with a parking brake system such that in the applied position retention is effected by a mechanical means, and the braking effect of
