BRAKE SYSTEM

1. GENERAL INFORMATION

Brake System

Even though a driver cuts off the power, while driving, the
vehicle continues to move due to the law of inertia.
Therefore, a braking device is needed to stop the vehicle.
The brake system normally uses the frictional discs that
converts the kinetic energy to the thermal energy by fric-
tional operation.

The brake system consists of the brake disc (front wheel),
brake disc or drum (rear wheel), parking brake (mechanical
type), master cylinder, booster, pedal and supply lines
(pipes and hoses).

Hydraulic Brake

Brake Pedal

This system uses the leverage effect and Pascal’s
principle. When depressing the brake pedal, the pedal
pressure is increased by booster and is delivered to mas-
ter cylinder to generate hydraulic pressure.

The hydraulic pressure generated by the master cylinder
is delivered to the brake caliper through the brake pipes or
hoses.

This hydraulic pressure pushes the brake calipers, ac-
cordingly the caliper pads are contacted to brake disc to
generate the braking force.

Brake pedal uses the leverage effect to apply bigger force
to the brake master cylinder.

Master Cylinder

Rear

Front

The brake master cylinder is designed to convert the force
from the brake master cylinder to the high hydraulic
pressure. The brake system uses the tandem type mas-
ter 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 pres-
sure generated by the primary piston is delivered to the
front wheels, and the hydraulic pressure generated by the
secondary piston is delivered to the rear wheels.

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 gen-
erated by vacuum pump in intake manifold and the atmo-
spheric pressure.

 1. 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 air flows into the chamber (B) through filter.
Then, the power piston (5) pushes the master cylinder
push rod (7) to assist the brake operation.

2. Pressure distribution after working

When releasing the brake pedal, the valve plunger (3) re-
turns 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).
