Abstract
A braking system for the brake of a fluid motor including a jack for releasing the brake and two selectors for controlling the flow of working fluid to the jack. The first selector is responsive to the supply of fluid to the motor to place the jack in communication with a supply pipe and the second selector is responsive to pressure in a bleed pipe connected to the fluid supply to the motor to place the supply pipe in communication with a supply of working fluid under pressure.
