110 Performance of braking systems

(1)  One sustained application of the brake of a light motor vehicle built after 1930, or a light combination that includes a light motor vehicle built after 1930, must be able to produce the performance specified in subregulations (2) , (3) , (4) , (5) , (6) and (7) –

(a) when the vehicle or combination is on a dry, smooth, level road surface, free from loose material; and

(b) whether or not the vehicle or combination is loaded; and

(c) without part of the vehicle or combination moving outside a straight path –

(i) centred on the longitudinal axis of the vehicle or combination before the brake was applied; and

(ii) 3.7 metres wide.

(2)  The braking system of a light motor vehicle or light combination with a gross mass less than 2.5 tonnes must bring the vehicle or combination from a speed of 35 kilometres per hour to a stop within –

(a) 12.5 metres when the service brake is applied; and

(b) 30 metres when the emergency brake is applied.

(3)  The braking system of a light motor vehicle or light combination with a gross mass of at least 2.5 tonnes must bring the vehicle or combination from a speed of 35 kilometres per hour to a stop within –

(a) 16.5 metres when the service brake is applied; and

(b) 40.5 metres when the emergency brake is applied.

(4)  The braking system of a light motor vehicle or light combination with a gross mass less than 2.5 tonnes must decelerate the vehicle or combination, from any speed at which the vehicle or combination can travel, by an average of at least –

(a) 3.8 metres a second per second when the service brake is applied; and

(b) 1.6 metres a second per second when the emergency brake is applied.
