Two means of making substantial improvements in brake balance are discussed. The first, the use of dynamic rather than static weights in braking power calculations has greatest value on loaded vehicles. Dynamic weights existing at 0.3 g deceleration are proposed as a standard. The second, load proportioned braking, is helpful on empty vehicles but must be used on all axles which have a substantial change in weight from the empty to the loaded condition. If used on only one unit of a combination vehicle, it may have a detrimental effect on brake balance.
