4.                                          Design REQUIREMENTS FOR TRAILERS UP TO 4.5 TONNES 'ATM'
4.1.                                    Every trailer must be equipped with an efficient 'Service Brake System'  which, with the exception of trailers equipped with an  'Over-run Braking System', must be designed so that the braking force can be progressively increased and decreased by means of the 'Control Signal' from the towing vehicle.
4.2.                                    In the case of trailers with a 'Gross Trailer Mass' of greater than 2 tonne, the 'Brake System' must operate on all wheels.
4.3.                                    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.
4.4.                                    Every trailer having a 'Gross Trailer Mass' over 2 tonnes must be equipped with an efficient 'Emergency Brake System' which will cause immediate automatic application of its 'Brakes' in the event of the trailer accidentally becoming disconnected from the drawing vehicle. 'Brakes' so applied must remain applied for at least 15 minutes.
4.5.                                    Trailers up to 4.5 tonnes 'ATM' are not required to comply with other clauses of this rule.
5.                                          GENERAL DESIGN REQUIREMENTS FOR TRAILERS OVER 4.5 TONNES 'ATM'
5.1.                                    A 'Service Brake System' must be fitted to all trailer wheels and be in accordance with the requirements of part 6.
5.2.                                    The trailer 'Brake System' must 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
