drawing vehicle from the driver's 'Seat' and, in the case of trailers with an 'Aggregate Trailer Mass' of greater than 2 tonne, operates on all wheels.

         38.2.0.2  The 'Brake System' on trailers with a 'Gross Trailer Mass' up to 2 tonnes may be actuated for both 'Service Brake System' and 'Secondary Brake System' by the over-run of the trailer.

         38.2.0.3  Every trailer having a 'Gross Trailer Mass' over 2 tonnes and every 'Semi-trailer' shall be equipped with an 'Emergency Brake System' which will cause immediate automatic application of its 'Brakes' in the event of the trailer or 'Semi-trailer' accidentally becoming disconnected from the drawing vehicle. 'Brakes' so applied shall remain applied for at least 15 minutes and shall have the performance prescribed for emergency brakes as prescribed in the Rule.

         38.2.0.4  Trailers with an 'Aggregate Trailer Mass' of up to 4.5 tonnes are not required to comply with other Sections of this Rule.

38.2.1.                          'Brake System'

38.2.1.1.                    A 'Service Brake System' shall be fitted to all trailer wheels and be in accordance with the requirements of clause 38.2.2 ('Service Brake System').

38.2.1.2.                    The trailer 'Brake System' shall be capable of being actuated from the towing vehicle by means of a connection between the trailer and towing vehicle with a performance not less than that specified for the 'Emergency Brake System' in clause 38.2.3 after any one failure in a 'Brake Device' in the trailer 'Brake System'.

38.2.1.3.                    A 'Parking Brake System 38/00' shall be fitted and shall meet the requirements of clause 38.2.4.

38.2.1.4.                    The trailer 'Brake System' must restrain the trailer automatically, in the event of a trailer break-away with a performance not less than that specified for the 'Emergency Brake System' specified in clause 38.2.3.

38.2.1.5.                    A 'Brake System' which utilises 'Stored Energy' to actuate the 'Service Brake System' shall be designed so that when the 'Supply Line' energy level is reduced at a rate of not less than 0.15E/sec (100 kPa/sec) the following conditions are met.

           (a) the 'Brake System' shall not start to automatically apply the 'Brakes' at a' Supply Line' energy level of more than 0.65 'E' (420 kPa) AND,

           (b) the 'Brake System' shall start to automatically apply the 'Brakes' at a 'Supply Line' energy level of not less than

               (i)  0.31 'E' (200 kPa) where the maximum braking effectiveness of the 'Brakes' so applied is dependent on 'Stored Fluid Energy' OR,

               (ii)  0.24 'E' (155 kPa) where the maximum braking effectiveness of the 'Brakes' so applied is not dependent on 'Stored Fluid Energy', AND

           (c) with the 'Supply Line' energy level at 0.0 'E' the braking effectiveness shall be at least that specified for the 'Emergency Brake System' in clause 38.2.3.2 ('Emergency Brake
