Figure 1 Normal Braking Hydraulic Circuit
ABS PRIMARY HYDRAULIC CIRCUIT AND SOLENOID VALVE FUNCTION (ABS WITHOUT TRACTION CONTROL)
The hydraulic diagram (Figure 2) shows the vehicle in the ABS braking mode. The diagram shows one wheel is slipping because the driver is attempting
to stop the vehicle at a faster rate than is allowed by the surface on which the tires are riding.
-
The normally open and normally closed valves modulate (build/decay) the brake hydraulic pressure as required.
-
The pump/motor is switched on so that the brake fluid from the low pressure accumulators is returned to the master cylinder circuits.
-
The brake fluid is routed to either the master cylinder or the wheel brake depending on the position of the normally open valve.
