32. Where a dynamic test is performed to check the effectiveness of the service brake, the test shall take place on a surface with a good asphalt or concrete coating that is dry, clean, not oily or greasy and with the tires inflated at the pressure determined by the manufacturer. If the test is performed by using the deceleration method or by measuring the breaking distance, the road vehicle shall be driven unloaded at 30 km/h and shall be capable of braking so as to reach maximum deceleration without locking the wheels. When braking, the vehicle in the centre of a lane 3.7 m in width shall not pull to the left or right so much that the lane limits are crossed; the test shall be performed without turning the steering wheel to correct the vehicle’s trajectory.
The result of the deceleration method shall be an average deceleration of at least 6 metres per square second for a vehicle whose gross vehicle weight rating is less than 4,500 kg; as for the braking distance method, the measured distance shall not exceed 5.8 m for a vehicle whose gross vehicle weight rating is less than 4,500 kg.
Where the brake is released, each wheel shall turn freely and no element of the brake system shall be damaged.
