4.2.2.9 Braking performance
4.2.2.9.1 General
The progressive characteristics of the brake are determined by linearity
measurements. A final, simple track test checks for smooth, safe, stopping
characteristics.
Conduct the braking-performance test on a fully-assembled bicycle after the brakes
have been subjected to the strength test detailed in 4.2.2.7, 4.2.2.8. Before testing
the bicycle, inflate the tyres and adjust the brakes all according to the
manufacturer's instructions, but in the case of rim-brakes to the maximum clearance
specified by the manufacturer.
4.2.2.9.2 Requirements
Where CARGO BIKE is fitted with secondary brake-levers attached to brake-levers,
bar-ends or aerodynamic extensions, separate tests shall be conducted for the
