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.

1. SYSTEM OVERVIEW
1) What is ABS?
When braking suddenly or braking on slippery roads, the vehicle keeps moving forward but the wheels
are locking and not rotating. If these happen, the vehicle may lose stability or rotate resulting in an
accident. ABS helps to maintain directional stability and control of the vehicle. ABS is designed to
secure more safety and increase the control of steering wheel during emergency braking situation. But,
ABS does not guarantee perfect safety beyond its physical limit. ABS in this vehicle contains EBD
function. In normal driving conditions, the brake system operates without ABS function.
2) What is EBD (Electronic Brake-force Distribution)?
EBD is an automobile brake technology that automatically varies the amount of force applied to each of a
vehicle's brakes, based on road conditions, speed, loading, etc. Always coupled with anti-lock braking
systems, EBD can apply more or less braking pressure to each wheel in order to maximize stopping
power whilst maintaining vehicular control. EBD does not operate when ABS is working.ABS effect according to braking conditions ▶
