A braking system includes a brake device 114 coupled with a lever assembly 124 to cause a braking force to be applied to the machine. A first linear actuator 138, preferably a hydraulic piston/cylinder, and a second linear actuator 122, preferably a worm screw 148 driven by electric motor 146, is actuated from a retracted position to an extended position based on a first braking input, preferably a brake pedal, and a second braking input, preferably a parking switch, respectively. A lever assembly 124 is actuated by one of the first linear actuator 138 and the second linear actuator 122. The lever assembly 124 includes a base that includes a slot 152. The second linear actuator 122 is slidably received within the slot 152, by pin 149. A first arm 172 and second arm 174 extends from the base is coupled to the first linear actuator 138 and the brake device 144, respectively. The first linear actuator 138 causes the lever assembly 124 to rotate independently from the second linear actuator 122 when the second linear actuator 122 is in the retracted position. |
