Original Abstract Submitted
A service brake system for a machine includes a brake assembly including a brake actuator and a brake spring. The brake actuator is movable in a brake application direction and in a brake disengagement direction. The brake spring is arranged to apply a spring force on the brake actuator in the brake application direction. The brake actuator has a first pressure chamber and a second pressure chamber. Pressurized fluid introduced into the first and second pressure chambers respectively applies a first and a second hydraulic force on the brake actuator in the brake disengagement direction counter to the spring force. A first pressurized fluid supply is in communication with the first pressure chamber for providing pressurized fluid to generate the first hydraulic force. A second pressurized fluid supply in communication with the second pressure chamber for providing pressurized fluid to generate the second hydraulic force.
