Brake pad: Brake pad is a component of disk brakes used in automotive and other applications.
Brake pad is steel backing plates with friction material bound to the surface that faces the brake disc.
Brake disc: The brake disc is a device for slowing or stopping the rotation of a wheel while it is in
motion.
Brake caliper: To stop the wheel, friction material in the form of brake pads (mounted on a device
called a brake caliper) is forced hydraulically against both sides of the disc. Friction causes the disc
and attached wheel to slow or stop.
Brake master cylinder: The brake master cylinder is a control device that converts non-hydraulic
pressure (commonly from a driver's foot) into hydraulic pressure, in order to move other device(s)
which are located at the other end of the hydraulic system, such as one or more slave cylinders. As
piston(s) move along the bore of the master cylinder, this movement is transferred through the
hydraulic fluid, to result in a movement of the slave cylinder(s). The hydraulic pressure created by
moving a piston (inside the bore of the master cylinder) toward the slave cylinder(s) compresses the
fluid evenly, but by varying the comparative surface-area of the master cylinder and/or each slave
cylinder, one will vary the amount of force and displacement applied to each slave cylinder (relative to
the amount of force and displacement that was applied to the master cylinder). -

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.
