Brakes have been advanced in the recent years through many developments. Previously all these years brake pads were
made of asbestos fiber which are very harmful in many ways. When vehicles apply brake, the asbestos gets wear down and
releases asbestos dust into the ambience and surrounding. This asbestos dust also gets entrapped inside the brake housing which
is also a vital problem to be considered. Hence when there is requirement to open the brake housing, the asbestos dust is released
into the air and the workers may accidentally inhale it without consciousness.
