A method and a mechanism for releasing a hydraulically actuated elevator brake system wherein the brake release mechanism includes a rotary pump, a crank handle to manually turn the rotary pump, a fluid supply port, a fluid return port, an output port for connection to a cylinder of the brake system, a rapid exhaust valve having an inlet port connected via the rotary pump to the fluid supply port, a cylinder port selectively connectable to the output port, and an exhaust port connected to the fluid return port. By turning the rotary pump, for example with the crank handle, a continuous flow of pressurized hydraulic fluid is delivered through the rapid exhaust valve and onto the brake cylinder, thereby releasing the hydraulic brake system.
