Pressure in the accumulators is maintained by the steering pump. The brake control manifold controls the oil flow to front brake accumulator (1), rear brake accumulator (2), and supply brake accumulator (3).
Front brake accumulator (1) is located next to the hydraulic tank and the steering system accumulators, and stores pressured oil for the front brake hydraulic system. Front brake accumulator (1) is a piston-type accumulator that is charged with nitrogen. Front brake accumulator (1) is a ready source of pressurized oil for the front brake system. Front brake accumulator (1) maintains a constant pressure by absorbing high or low-pressure surges. There is a nitrogen charge valve on the top of the accumulator. Front brake accumulator (1) should be pre-charged to approximately
Rear brake accumulator (2) is located behind the cab and mounted to the service center enclosure. Rear brake accumulator (2) is a piston type accumulator that is charged with nitrogen gas. Rear brake accumulator (2) is a ready source of pressurized oil for the rear brake system. Rear brake accumulator (2) maintains a constant pressure by absorbing high or low-pressure surges. There is a charge valve located on top of the accumulator. Rear brake accumulator (2) should be pre-charged to approximately
Supply brake accumulator (3) is located next to rear brake accumulator (2). Supply brake accumulator (3) provides pressure to release the parking brakes and to supplement the front and rear brake accumulators.
