assistance is immediately energised by a pump driven independently of the vehicle engine.
35.2.3.8.                    Every motor vehicle used to haul a trailer (including a 'Semi-trailer') shall be so equipped that its brake system shall remain operative and have the performance of the Laden Secondary Brake Test (item 7 of clause 35.3.3) in the event of the trailer becoming disconnected, howsoever caused.
35.2.4.                          Special Provisions for All Vehicles with 'Hydraulic Brake Systems'
35.2.4.1.                    In cases where the service brake system incorporates a master cylinder, each service brake sub system serviced by the master cylinder shall have either:
35.2.4.1.1.              a reservoir which contains fluid exclusively for the use of that service brake sub-system; or
35.2.4.1.2.              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 shall be not less than the volume displaced by the master cylinder piston servicing the sub-system, during a full stroke of the piston.
35.2.4.2.                    The capacity of each reservoir shall be not less than the fluid displacement resulting when all the wheel cylinders or caliper 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:
35.2.4.2.1.              the limit recommended by the 'Manufacturer';
35.2.4.2.2.              level with rivet or bolt heads on riveted or bolted linings;
35.2.4.2.3.              within 3 mm of the pad mounting surface on bonded pads; or
35.2.4.2.4.              within the following distance of the shoe mounting surface on bonded linings:

Nominal bonded    ≤5 mm   >5 mm   >10 mm  >13 mm  >19 mm
Lining thickness          ≤10 mm  ≤13 mm  ≤19 mm
Worn thickness    0.8 mm  3 mm    5 mm    6 mm    7 mm

35.2.4.3.                    Each 'Brake Power Unit 35/00' shall be provided with a reservoir of capacity not less than the total capacity of the reservoirs required under the requirements of clause 35.2.4.2 plus the fluid displacement necessary to charge the piston(s) or accumulator(s)) provided for the purpose of storing energy.
35.2.4.4.                    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" shall 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 shall be of
