<p>A braking system has a liquid-cooled brake (1) having a housing (2) containing at least one rotary braking element (3) coupled to a rotary member (3A) to be braked, and a relatively fixed surface for engagement by the braking element to effect braking thereof. The system includes actuator means (4) operable to bring the braking element and fixed surface into braking engagement, and fluid flow means (9) for supplying cooling liquid to the brake during actuation thereof. The fluid flow means serves both to charge the brake with cooling liquid during brake actuation and to withdraw liquid from the brake for cooling and may be arranged to act in proportion to brake actuation energy input.</p> |
