ABS HYDRAULIC FUNCTION DRAWING

The ABS uses 2 channels (2 hydraulic systems) with the
hydraulic control method being as follows.
It controls the front and rear wheels on the same side
with select-low and drives the solenoid valve including
the one for the front wheel. For example, when either
the front or rear wheel on the right side is about to lock,
it maintains or loosely controls the solenoid valve
including the one for the front right wheel. And in order
to prevent locking of one rear wheel, there is a select-
low valve and the rear right and left wheels are
controlled mechanically by select-low. Consequently, a
total of three wheels - the front right or left wheel and the
Anti-lock Braking System (ABS)
rear right and left wheels - are controlled hydraulically at
the same time.
Also, if vehicle speed exceeds approximately 8 km/h
(5.0 mph), the brake hydraulic pressure control is ap-
plied and when it becomes less than approximately 3
km/h (2.0 mph), the control is completed. Select-low:
this is a method of providing the same hydraulic control
to both wheels when either wheel is about to lock,
matching it to the side about to lock, or a method to
control by matching pressure to the low side.
