 1.                               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 5.6.2 plus the fluid displacement necessary to charge the piston(s) or accumulator(s) provided for the purpose of storing energy.
 2.                               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.
 1.                                     Special provisions for systems using 'Stored Energy' (except 'Spring Brake Systems')
     1.                               Any 'Stored Energy' device for the operation or to assist in the operation of the braking system, must be so protected that failure of the device generating the energy does not result in depletion of the 'Stored Energy'.
     2.                               For systems incorporating 'Brake Power Units 35/...', the combined volume of all 'Brake Power Unit 35/...' devices at positive pressure must be not less than 12 times the combined volume of all the service brake chambers.
         1.                         The volume of a brake chamber of a type specified in Table 4 is taken as being either the rated volume listed in this table or the actual volume of the brake chamber at the maximum travel of the brake piston/pushrod, whichever is lower.
         2.                         The volume of a brake chamber not listed in Table 4 is the actual volume of the brake chamber at the maximum travel of the brake piston/pushrod.
     3.                               Any device generating energy at positive pressure for a 'Brake Power Unit 35/...' must be of sufficient capacity to increase the pressure in the 'Stored Energy' device(s) actually fitted to the vehicle from 85 per cent of the 'Average Operating Pressure' to the 'Average Operating Pressure' with the vehicle's engine operating at the 'Manufacturer' recommended maximum engine speed within a time given by the expression:
 1.                               In clause 5.7.3, 'Brake Power Unit 35/...' test capacity is:
          1.                              the minimum combined volume of all the service brake chambers required by clause 5.7.2 above, plus;
          2.                              in the case of a motor vehicle equipped to tow a trailer which uses air at a positive pressure, an additional 1.0 litre per tonne of 'Rated Towing Capacity' to allow for trailer service chambers.
 1.                         For vehicles with a 'Gross Combination Mass' in excess of
