<div class="htmlview paragraph">The distribution of the braking forces between axles has influence to the vehicle's braking ability, braking behaviour, and safety in traffic. In designing of brakes it is important to meet the most essential demands which are operating environment, structural properties of a vehicle, basic dimensioning of the brake mechanisms, and the controllability of braking forces as well as regulations on brakes. This paper introduces a study of the results during braking of 2- and 3-axle lorry and concentrates on the fulfilment of the braking force distribution according to the regulations in Finland. The friction requirements are compared with the regulations.</div>
