35.5.10.1.                This procedure is not applicable to vehicles with brake assemblies which have been tested in accordance with the requirements of clause 35.5.9.2.
35.5.10.2.                The vehicle shall be accelerated over a distance not exceeding 1.6 km from the final speed attained at the conclusion of the deceleration mode of the Service Brake Fade Test to the initial speed specified in clause 35.3.3 (Item 10) and the test carried out in accordance with that Item. The vehicle shall be deemed to satisfy the requirements of this test if the deceleration achieved is not less than that specified in clause 35.3.3 (Item 10).
35.5.11.                      Service Brake Water Conditioning Procedure
         35.5.11.1.0. For Forward-control Passenger Vehicles (MB), Off-road Passenger Vehicles (MC) and Light Omnibus up to 3.5 tonne 'GVM', up to 12 seats (MD1):
Service brake water conditioning shall be carried out in accordance with the requirements of either clause 35.5.11.1 or clause 35.5.11.2.
35.5.11.1.                Water Immersion The vehicle shall be driven with the service brake released through water of depth of not less than 60 per cent of the 'Static Loaded Tyre Radius' of the tyres fitted, for a period of at least 2 minutes. During such period, the vehicle speed shall not exceed 10 km/h and for at least one minute, shall not be less than 5 km/h. For the purpose of this clause changes from "drive" to "reverse" and "reverse" to "drive" shall be considered as continuous driving.
35.5.11.2.                Water Spray The braking surfaces of all brake assemblies fitted to the vehicle shall be simultaneously and continuously wetted for a period of not less than 5 minutes. The rate of delivery of water to each brake assembly shall not be less than 25 litres per minute. In the case of drum brake assemblies the water flow shall be introduced through an aperture in the brake backing plate.
35.5.12.                      Service Brake Water Recovery Procedure
         35.5.12.0 For Forward-control Passenger Vehicles (MB), Off-road Passenger Vehicles (MC) and Light Omnibus up to 3.5 tonne 'GVM', up to 12 seats (MD1).
35.5.12.1.                Immediately upon completion of the Service Brake Water Conditioning Procedure the vehicle shall be accelerated and the drive train shall be employed to attain initial speed appropriate to its category as specified in
clause 35.5.10. Continue at this speed until the total distance not exceeding 1.6 km has been travelled and then decelerate at a sustained deceleration of not less than 2.0 m/s2 until stationary. This sequence shall be repeated 3 times without interruption. The brakes shall not be
applied except for the deceleration specified.
35.5.12.2.                The Service Brake Water Recovery Procedure shall be followed immediately by the Service Brake Water Effectiveness Check.
