A winch brake device that is used for a work machine and generates a braking force on the basis of a brake manipulation, includes a pressing member that brings braking members into pressure contact with each other to generate the braking force, a first brake cylinder that applies a first pressing force for bringing the braking members into pressure contact with each other to the pressing member, and a second brake cylinder that applies a second pressing force different from the first pressing force to the pressing member. The first brake cylinder and the second brake cylinder are capable of applying the first pressing force or the second pressing force independently of each other.
