1. OVERVIEW
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 frictional 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 master 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,
accordingly 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.

4WD - Front/Rear wheel speed
sensor
2WD - Front wheel speed sensor
2WD - Rear wheel speed sensor
ECU (Electronic Control Unit) 1.
ECU calculates the wheel speed, acceleration and
deceleration with the information from wheel
speed sensor, and determines the wheel slip to
control the valve and motor.
HU (Hydraulic Unit) 2.
The hydraulic circuit contains the primary circuit
and secondary circuit for ABS operation. This unit
controls the hydraulic pressure to each wheel. If
the system needs ABS operation, the valves in
the unit operate to control HOLD, RISE and
DUMP according to ECU control logic.
Motor 3.
The motor is operated when ABS is activated. The
cam-shaped output shaft of the motor enables the
brake system to receive and supply the brake fluid
during the motor operation.
Wheel speed sensor ▶
Wheel speed sensor sends the data detected by
tone wheel to HECU.
HECU ▶
Rear wheel speed sensor in 2WD vehicle is
different from that in 4WD vehicle.

G-sensor (only for 4WD) ▶
For the vehicle with the ABS, a speed difference
between the wheels is not noticeable as all the
wheels are slipping during abrupt braking.
Therefore, the vehicle needs the speed
information from other sensors other than the
wheel speed sensor. On the 2WD vehicle, there
is not large difference between the vehicle speed
reduction and actual wheel speed reduction in
the event of braking since the driving wheels are
in the front. So, the ABS HECU can control the
vehicle, based on a calculation value. But, on the
4WD vehicle, if a speed reduction occurs in the
front or rear of the vehicle, it affects the other side
wheel. In other words, braking the rear wheels
induces also a large speed reduction in the front
wheels. The longitudinal acceleration sensor is
used for this case. It controls the ABS by using
the signals from the sensor during abrupt braking
and acceleration.G-sensor
