BRAKS SYSTEM
2. BRAKE SYSTEM OPERATION PROCESS
1) 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
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).
2) Hydraulic Brake
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 maste
r
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.
3) Brake Pedal
Brake pedal uses the leverage effect to
apply bigger force to the brake master
cylinder.
