Hydraulic Control Assembly - Antilock Brakes: Description and Operation
During Normal Braking
Since no current is supplied to the inlet and outlet solenoid valves, no solenoid valve attracting force is generated. So the valves remain stationary.
Accordingly, the inlet port of the inlet solenoid valve is in an opened state, whereas the outlet port of the outlet solenoid valve is in a closed state. So the
fluid pressure of the master cylinder is transmitted to the wheel cylinder to produce a brake force in the wheel cylinder.
