A braking system may include a brake assembly having a brake shaft and a brake lever coupled to the brake shaft. The system may also include a brake cylinder having a first chamber, a second chamber, a piston positioned between the chambers and a piston rod extending outwardly from the piston. The piston rod may be configured to be coupled to the brake shaft such that movement of the piston rod results in rotation of the brake shaft. In addition, the system may include a first valve configured to control a supply of working fluid to the first chamber and a second valve configured to control a supply of the working fluid to the second chamber. By adjusting a position of the first valve and/or the second valve, a braking force applied between the brake assembly and a drum of the draw works may be controlled.
