(1) Parking brake (2) Brake pack (3) Front axle (4) Hydraulic tank (5) Supply oil from the pressure reducing valve which is located in the Main control valve (implement). (6) Brake pedal (7) Service brake pressure switch (8) Rear axle (9) Brake cylinder (10) Parking brake switch (11) Parking brake lever (12) Parking brake cableThe braking system has the following main components:
Brake pack
Brake pedal
Brake cylinder
Service brake pressure switch
Parking brake leverBrake Packs
Oil immersed multiple brake discs are located in brake packs (2) at each side of the differential on front axle (3) .Brake Pedal
Brake pedal (6) is connected to a mechanical linkage in order to operate brake cylinder (9). When the brake pedal is pressed, the brake cylinder creates high oil pressure that is transmitted through the brake lines in order to engage the brake discs in the brake packs on front axle (3) .Brake Cylinder
The operation of brake cylinder (9) is assisted by boost pressure from the implement system. The boost pressure comes from the pressure reducing valve. The pressure reducing valve is located in the main control valve group (implement). Any excessive oil from the brake cylinder is returned back to tank (4) .Service Brake Pressure Switch
Service brake pressure switch (7) is used in conjunction with the transmission neutralizer control (switch) on the dash panel to disengage the transmission when force is applied to the brake pedal. When brake pedal (6) is released, the transmission is engaged at the speed which was previously selected.Parking Brake Lever
Parking brake lever (11) is connected to parking brake cable (12) in order to operate parking brake (1) on the front axle. Parking brake switch (10) signals the machine ECM that the parking brake is engaged. Then, the machine ECM sends a signal in order to neutralize the transmission when the lever for the parking brake is pulled slightly upward.
