be driven with the wetting equipment operating for a distance of not less than 1.0 km at the test initial vehicle speed prior to the application of the brakes being tested.

4.15.7                            For drum brakes the prescribed amount of water must be distributed equally on either side of the braking device (that is, on the stationary back plate and the rotating drum) from nozzles so positioned as to be two-thirds of the distance from the outer circumference of the rotating drum to the wheel hub.

4.15.8                            Subject to the requirements of clause 4.15.7 and to the requirement that no nozzle must be within 15° of or coincident with a ventilation or inspection port on the stationary back plate, the test equipment for drum brakes must be so positioned as to obtain the optimum uninterrupted application of water.

4.15.9                            Performance Level Attained with Brake Subject to Wetting
4.15.9.1                      Each independently actuated service brake must be tested in accordance with the procedures laid down in clause 4.14 "Second Base Line Check Procedure".

4.15.9.2                      The mean deceleration attained with wet brake(s) between 0.5 and 1.0 second after application must be at least 60 per cent of that attained with dry brake(s) during the Second Base Line Check when the same 'Control' force is applied.  The 'Control' force used, which must be applied as quickly as possible, must be equivalent to that required to attain an 'Average Deceleration' of 3.0  ±  0.2 m/s2 with dry brake(s).

4.15.9.3                      At no time during the wet brake test must the deceleration exceed 120 per cent of that attained with dry brakes.
