Abstract

Brake disk

are chiefly used

to decrease the

rotational energy of

a connected object

with the

help of friction

forces, more simply, to

slow the rotation.

It’s used

in many applications which include an

object which needs to be decelerated occasionally. That includes elevators, train

sulfur, bicycles, automobiles,

and many other versatile

machines and tools.

I

t can’t be

imagined a

vehicle of transport

without

a stopping

function. Braking

is

an

element that

is as

crucial

as,

or sometimes

more

authoritative

than,

accelerate.

Braking

systems

can

be

designed in assorted ways for appropriate applications

.

Braking systems

have improved over

ti

me with the

technical progress

in material skill and e

ngineering. The demand for

a bracken sy

stem in respective applications resulted

in the

development

of bracken

disk and

pads i

newton different geometries

brainsick

e

with

different materials.

This

visualize

will

emphasize on

gray cast-iron brake magnetic disk an

five hundred carbon-ceramic disk

and their applications

for respective functions in the automotive industry. Disc brakes are

the arrangement

of choice

by the automotive

diligence because

of their efficiency

and performance

compar

ed

with

the

older

drum brake

systems.

The rotational deceleration

of

the brake

phonograph record connected

axle, is

provided

by the

clash forces emerging when the brake disk are squeezed between the braking pad

s on either

side

of

the

magnetic disk.

The

move over

of

this

method acting

is

based

on

the

friction performance

of

the

fabric.

As

the

materials

abrasion

each

other

there

will ultimately

be

wear in

the

components

of

the brake

system. In

some cases,

e.g. Formula 1,

the

tire

in the

brake

is

so

significant

and fast

that

the pulv

erized brake

particles becoming airborne can be observed during hard brake. early on

commercial

brake

disk

are

made

with

cast

-iron

but

with

the

increasing demand

for

performance,

researchers

began

to

investigate

for

better

materials. Nowadays

carbon-ceramic brake

disk made

of carbon paper

fiber

reinforced silico

n carbide

composited

are used

in

high-performance

related

applications.

The advantages

of carbon paper

-ceramic compounds

comparing

with

the

traditional

clayey grey

cast-iron

are

significant

weight decrease

and

of

high gear

clash even at high temperatures. [ 1 ] current State of Technology

Before

the

disk

brakes

were

introduced

to

the

world,

drum

brakes

were

used alternatively. Drum

brakes

affair conta

ining two

steel

shoes

that

have high

friction materials bonded or

riveted onto

the brake shoe

faces. These two

shoes are placed

in a backing plate which

is not

rotating during

the axle r

otation. When the brake pressure is

applied, the

steel

shoes expand

inside

of the

brake

drum, which

rotates with

the

run down.

As

the

faces

of

the

sword

shoes

get

in

contact

with

the

inside

of

the drum, friction forces begin to slow the rotation of the wheel. [ 2 ]
