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.

Braking distance & stopping distance

▶

Stopping distance = free running distance + braking distance

What is stopping distance?

A certain distance (free running distance + braking distance) is needed from the moment an obstacle

appears ahead until you bring your vehicle to a complete stop. This is called as stopping distance.

What is braking distance?

Tire slip occurs until the vehicle stops completely when the the brake is applied.

This slip is what we call a braking distance.

What is free running distance?

The free running distance is the time from the driver sees the obstacles and begins to prepare for

depressing the brake pedal until the moment the brake pedal is depressed.
