TORQUE ON DEMAND
(3) Electro Magnetic Clutch (EMC)
EMC consists of coil and housing. TOD control unit controls EMC by controlling duty cycle
according to the road and driving conditions. These controls use the continuity time and amount
of electric current to determine the torque to be transmitted to front wheels.

BRAKS SYSTEM
RODIUS 2005.07

4) Master Cylinder
The brake master cylinder is designed to
convert the force from the brake maste
r
cylinder to the high hydraulic pressure. The
brake system uses the tandem type master
cylinder with in-line 2 pistons.
The in-line 2 pistons generate the hydraulic
pressure. The piston cup on the piston keeps
the sealing conditions in cylinder and
prevents the oil leaks. The hydraulic
pressure generated by the primary piston is
delivered to the front wheels, and the
hydraulic pressure generated by the
secondary piston is delivered to the rea
r
wheels.
5) Brake Booster
The brake booster is a power assist device for brake system. It relieves the pedal depressing
force by using the pressure difference between the vacuum pressure generated by vacuum
pump in intake manifold and the atmospheric pressure.
▶Pressure distribution at working
When depressing the brake pedal, the push
rod (1) in booster pushes the poppet (2) and
valve plunger (3). The poppet (2) pushes the
power piston seat (5) resulting in closing the
vacuum valve (9). The chamber (A) and (B)
in power cylinder are isolated and the valve
plunger (3) is separated from the poppet (2).
And then the air valve (6) opens and ai
r
flows into the chamber (B) through filter.
Then, the power piston (5) pushes the
master cylinder push rod (7) to assist the
brake operation.
▶Pressure distribution after working
When releasing the brake pedal, the valve
plunger (3) returns back to the original
position by return spring (4) and the air valve
(6) closes. At this time, the vacuum valve (9)
opens and the pressure difference between
chamber (A) and (B) in power cylinder is
eliminated. Accordingly, the power piston (5)
returns back to original position by the
reaction of master cylinder (10) and the
diaphragm return spring (8).

BRAKS SYSTEM
6) Master Cylider & Booster
ABS system is basically equipped to STAVIC.
Vehicle which adapted ESP system in option has two pressure sensors under master cylinder
and these two sensor are used for BAS (Brake Assist System) system.
Do not disassemble the brake oil pressure sensors These can not be reinstalled of
disassembled.
After reinstall the reserver tank perform a air bleeding of brake system
