System 38/00'.   Operation of the 'Control' must cause the pressure in the 'Supply Line 35/...' to drop below 35 kPa and remain below 35 kPa independently of the motor vehicle's 'Service Brake System'.
4.5.10.1.                    The 'Control' which actuates this function must be located so that it is readily accessible to the driver in the normal driving position and, marked with the words 'TRAILER EMERGENCY  BRAKES' and a description of how to operate the control, e.g. 'TRAILER EMERGENCY BRAKES – PULL'.  The 'Control' must also be marked with the words 'NOT FOR PARKING'.  The letters must be not less than 5 mm high.  Letters and background must be contrasting colours, one of which is red.
4.6.                                    Special Provisions for All Vehicles with 'Hydraulic Brake Systems'
4.6.1.                              In cases where the 'Service Brake System' incorporates a master cylinder, each service brake sub-system serviced by the master cylinder must have either:
4.6.1.1.                                      a reservoir which contains fluid exclusively for the use of that service brake sub-system; or
4.6.1.2.                                      a reservoir which contains fluid for the use of 2 or more service brake sub-systems, in which case that part of the reservoir capacity provided exclusively for the use of each service brake sub-system must be not less than the volume displaced by the master cylinder piston servicing the sub-system, during a full stroke of the piston.
4.6.2.                                            The capacity of each reservoir must be not less than the fluid displacement resulting when all the wheel cylinders or calliper pistons serviced by the reservoir move from a new-lining, fully-retracted position, as adjusted according to the 'Manufacturer's' recommendations to a fully-worn, fully-applied position.  For the purpose of this clause, "fully-worn, fully-applied" means that the lining is worn to whichever of the following conditions allows the greatest shoe or pad movement:
4.6.2.1.                        the limit recommended by the 'Manufacturer';
4.6.2.2.                        level with rivet or bolt heads on riveted or bolted linings;
4.6.2.3.                        within 3 mm of the pad mounting surface on bonded pads; or
4.6.2.4.                        within the following distance of the shoe mounting surface on bonded linings:

       Nominal Bonded         Lining Thickness         Worn thickness
       < 5 mm                                           0.8 mm
       > 5 mm                 < 10 mm                  3 mm
       > 10 mm                < 13 mm                  5 mm
       >13 mm                 < 19 mm                  6 mm
       >19 mm                                          7 mm

4.6.3.                              Each 'Brake Power Unit 35/...' must be provided with a reservoir of capacity not less than the total capacity of the reservoirs required under the requirements of clause 4.6.2 plus the fluid displacement necessary to charge the piston(s) or accumulator(s) provided for the purpose of storing energy.
4.6.4.                              A statement specifying the type of fluid to be used in the brake system and displaying at least the words "WARNING.  Clean filler cap
