Retention of Directional Control When Braking

Abstract

<div class="htmlview paragraph">Ways of preventing the loss of directional control, which frequently occurs during emergencies, are described. These include special braking techniques, changes in brake distribution, balancing of brake reactions, and nonlocking braking systems.</div> <div class="htmlview paragraph">Details are given of a particular application of a nonlocking braking system. Test results at speeds up to 140 mph of the braking performance and directional stability are given; reductions of up to 35% in braking distances were obtained on some wet surfaces.</div> <div class="htmlview paragraph">Attention is drawn to the considerable reduction in tire adhesion, which occurs when a wheel locks and which can be avoided by antilocking braking systems.</div>
