Typical ExampleSection View (3) Wheel spindle housing (4) Cover (5) Brake hub (6) Shims (7) Sprocket (8) Plates (9) Brake discs (10) Piston (11) Oil compartment (12) Duo-Cone seal (13) Wheel spindle (14) SpringPower from the differential flows through the drive chain to sprocket (7) . Inside wheel spindle housing (3) , the sprocket turns wheel spindle (13) , brake hub (5) , and brake discs (9) . The drive wheels are connected to the wheel spindle.The four disc type brakes are used for the service brake system. There is one disc type brake in each wheel spindle housing (3) . The brakes are cooled through the oil in tandem housing (2) . The service brakes are activated by pressurized oil from the brake control valve. There is a Duo-Cone seal (12) that is located between the wheel spindle (13) and the wheel spindle housing (3) . The Duo-Cone seal will seal in the oil. The Duo-Cone seal will also keep out the dirt, the water, and the other contaminants.Plates (8) are held in the stationary position by dowels located in the wheel spindle housing (3) . Brake discs (9) are splined onto brake hub (5) . The brake hub is splined onto wheel spindle (13) .

(16) Service brake pedal (17) Rod (18) Brake control valveThe braking and the hydraulic fan pump sends oil to the control manifold. The control manifold contains valves that control the pressure in the brake system. The control manifold contains a pressure sensor that sends an electronic signal to the monitoring system. When the brake pressure is low, the monitoring system turns on a brake warning lamp (15) .When you depress the service brake pedal (16) , a rod (17) actuates brake control valve (18) . Then, the brake control valve (18) for the service brakes will send pressurized oil from the brake accumulators to the service brakes. The position of the pedal regulates the amount of oil pressure to the brakes.Pressurized oil flows through oil inlet port (1) into oil compartment (11) . Oil then moves piston (10) against plates (8) and brake discs (9) . The piston pushes the discs against wheel spindle housing (3) . As oil pressure increases, the piston is forced against the discs. This will cause friction between the discs. As the friction increases, the brake discs (9) , brake hub (5) , and wheel spindle (13) will start to slow down, since the plates (8) and wheel spindle housing (3) cannot turn. The brakes are in BRAKE ON position, but the brakes are not fully engaged.If the operator continues to depress the pedal downward, oil pressure will increase in oil compartment (11) . The friction between the discs will then become great enough to stop the brake discs (9) , the brake hub (5) , and the wheel spindle (13) . Oil
