Hydraulic Control Assembly - Antilock Brakes: Description and Operation
NORMAL POSITION (Pressure build-Up)
In normal position. the solenoid valve is de-energized. The piston is pressed down toward the normal position of the return spring. The brake fluid
is now able to flow freely from the master cylinder out through the solenoid valve to the wheel cylinder. This position is the normal position in
braking without ABS control and the pressure build-up position in ABS control.
In ABS control, the control module can run up to ten control cycles per second.
