NORMAL BRAKING HYDRAULIC CIRCUIT AND
SOLENOID VALVE FUNCTION
The hydraulic diagram (Fig. 11) shows the vehicle
in the normal braking mode of the base brake
hydraulic system. The diagram shows no wheel spin
or slip occurring relative to the speed of the vehicle.
The driver is applying the brake pedal which builds
pressure in the brake hydraulic system to engage the
brakes and stop the vehicle.
