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).

3. FFF GENERAL INFORMATION
The system is to increase the coolant temperature quickly by firing diesel fuel in the burner that
is installed in engine cooling system when in winter time the ambient temperature and engine
coolant temperature is low. (Option)
FFH System consists of independent fuel lines, fuel pump, coolant circuit, coolant ciculation
pump, electrical glow plug and exhaust system by driver’s intention because FFH system
is automatically.
Operated according to the coolant temperature and the ambient temperature.
FFH system operates up to more than 2 minutes to burn the residual fuel inside the system
when driver stop the engine during its operation. Therefore, a certain period of FFH operation
after stopping the engine is not a malfunction.
