BRAKE CIRCUIT
The 830E truck is equipped with hydraulic actuated disc brakes. The front brakes have three calipers applying braking effort to a single disc on each wheel. The rear brakes have two (armature-speed) discs with one caliper per disc. Each rear outboard disc also contains a parking brake caliper.
The fundamental function of the brake system is to provide an operator the control he needs to stop the truck in either a slow modulating fashion or in as short a distance as reasonably possible.
Outlined below are the functions that are necessary for safe truck operation:
1. Warn the operator as soon as practical of a serious or potentially serious loss of brake pressure so proper action can be taken to stop the truck before the secondary system is exhausted of power.
2. Provide secondary brake circuits such that any single failure leaves the truck with sufficient stopping power.
3. Automatically apply service brakes if low pressure warnings are ignored and pressures continue to decrease.
4. Wheel brake lock to relieve the operator from holding the brake pedal while at the dump or shovel.
5. Spring applied park brake for holding, not stopping, the truck during periods other than loading or dumping.
6. Brake system that is easy to diagnose and perform necessary service.
The following brake circuit description should be used in conjunction with the hydraulic brake system schematic, refer to Section "R".
The brake system consists of two major valve components; the dual circuit treadle valve (heart of the system) and brake manifold. The dual circuit treadle valve is the only component located in the operator's cab.
The remainder of the system, including the brake manifold, circuit accumulators, and electrical components, are located in a weatherproof cabinet behind the cab. This cabinet is accessible for diagnostic and service work.
The brake manifold contains dual circuit isolation check valves, accumulator bleed down valves, and valves for brake lock, park brake and automatic apply functions. All of these components are screw-in cartridge type valves.
In the 830E truck, there are two independent means of brake actuation, the service brake pedal and brake lock switch.
SERVICE BRAKE CIRCUIT OPERATION
This portion of the system provides the operator the precise control he needs to modulate (feather) brake pressure to slowly stop the truck or develop full brake effort to stop as quickly as possible. The heart of this circuit is the treadle operated dual circuit brake valve.
