Brake Pedals (1) Left brake pedal (2) Right brake pedal (3) Lock bar (4) Control valve (5) oil reservoir The service brake control consists of a control valve (4), two control pedals (1) and (2) with a lock bar (3), and a oil reservoir (5) .The left brake pedal (1) controls the left side of service brake control valve and the left rear brakes. The right brake pedal (2) controls the right side of service brake control valve and the right rear brakes. The left and right brake pedals are connected together by the lock bar (3). The lock bar (3) allows both brake pedals to be applied together.Unlock the lock bar (3) to aid in maneuvering in tight quarters. Unlock the lock bar (3) in first gear only. Use the brake pedals with the steering wheel in order to make sharp turns. Use the left brake pedal to help with sharp left turns. Use the right brake pedal to help with sharp right turns.Supply oil from the reservoir enters the service brake control valve through the supply port. When the operator depresses one brake pedal, oil is sent from one side of the valve to the same side service brake. The rear axle contains the service brakes. Refer to Systems Operation, "Axle (Rear)" and Systems Operation, "Drive and Steering Axle (Rear)" for more information on the service brakes.The brake pedal travel determines the force that is exerted by the brake piston. The braking force increases as the travel of the brake pedal increases. When the operator releases the brake pedal, the oil pressure to the service brake is released.
