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 before removing" must be permanently affixed, stamped, engraved or embossed with letters not less than 3 mm high, either on or partially within 150 mm of one brake fluid reservoir filler plug or cap and totally within 300 mm of all reservoir filler plugs or caps.  If not stamped, engraved or embossed, the lettering must be of a contrasting colour to that of the background.

4.7.                                    Special Provisions for Systems Using 'Stored Energy' (except 'Spring Brake Systems')

4.7.1.                              Any 'Stored Energy' device for the operation or to assist in the
