Oil immersed multiple brake discs (1) are located at each side of the differential in the front axle and in the rear axle.
The brake pedal is connected to a mechanical linkage in order to operate brake cylinder (master) (5). When the brake pedal is pressed, oil pressure is transmitted from the brake cylinder (master) in order to operate brake cylinder (boost) (4). The operation of the brake cylinder (boost) creates high pressure oil which is transmitted through the brake lines in order to engage the brake discs at each axle.
The operation of the brake cylinder (boost) is assisted by boost pressure from the implement pilot system. The implement pilot system is connected to the brake cylinder (boost) from pilot valve (2). The brake cylinder (master) and the brake cylinder (boost) are automatically topped up with oil from brake reservoir (7).
Pressure switch (3) is used in conjunction with the transmission neutralizer control (switch) on the dash panel to disengage the transmission when pressure is applied to the brake pedal. When the brake pedal is released, the transmission is engaged at the speed which was previously selected.
Lever (11) for the parking brake is connected to cable (10) in order to operate the brake discs in the front axle. Parking brake switch (9) disengages the transmission when the lever for the parking brake is pulled slightly upward.
