Brakes use friction to convert the kinetic energy of a moving vehicle into heat energy via brake pads or shoes pressing against a rotating brake drum or disc. Hydraulic brakes utilize incompressible brake fluid and Pascal's law to transmit pressure evenly to brake components attached to each wheel, allowing for equal braking force. Disc brakes use calipers to squeeze brake pads against a rotor attached to the wheel, while drum brakes use shoes that expand outward to press against a rotating drum enclosed within the brake assembly.
The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.
1) Suspension is the term given to the
system of springs, shock absorbers and
linkages that connect a vehicle to its
wheels
3) Serve a dual purpose – contributing to the
car's handling and braking.
2) Protects the vehicle itself and any cargo or
luggage from damage and wear

Clutch is a mechanism which enables the rotary motion of one shaft to be transmitted, when desired, to a second shaft the axis of which is coincident with that of first.
Clutch is used to engage or disengage the engine to the transmission or gear box.
The suspension System of an automobile is one which separates the wheel/axle assembly from the body. The primary function of the suspension system is to isolate the vehicle structure from shocks & vibration due to irregularities of the road surface.

“An object remains in its state of rest or in motion until and unless acted upon by an external force” Newton’s first law of motion, this law by Sir Isaac Newton gave rise to the development of braking system in an automobile, developing an automobile vehicle not only requires the power source but also the efficient braking system as higher the horse power higher will be the brake force required to stop or de accelerate that vehicle. This thought gave rise to many researches in the field of braking and results in its evolution due to which today we have flexibility in choosing a suitable braking system according to our need. So let’s just start our article with the curiosity about the various types of braking system.
In an automobile vehicle, a braking system is an arrangement of various linkages and components (brake lines or mechanical linkages, brake drum or brake disc , master cylinder or fulcrums etc) that are arranged in such a fashion that it converts the vehicle’s kinetic energy into the heat energy which in turn stops or de accelerate the vehicle.
The conversion of kinetic energy into heat energy is a function of frictional force generated by the frictional contact between brake shoes and moving drum or disc of a braking system.
A balance bar (also called a bias bar) on dual master cylinder systems, divides the force from the brake pedal to the two master cylinders . It is called a “balance bar” because that is exactly what it does.

3. WORKING OF BRAKES
• A COMMON MISCONCEPTION ABOUT BRAKES IS THAT BRAKES SQUEEZE
AGAINST A DRUM OR DISC, AND THE PRESSURE OF THE SQUEEZING ACTION
SLOWS THE VEHICLE DOWN. THIS IS IN FACT A PART OF THE REASON FOR
SLOWING DOWN A VEHICLE.
• ACTUALLY BRAKES USE FRICTION OF BRAKE SHOES AND DRUMS TO CONVERT
KINETIC ENERGY DEVELOPED BY THE VEHICLE INTO HEAT ENERGY.
• WHEN WE APPLY BRAKES, THE PADS OR SHOES THAT PRESS AGAINST THE BRAKE
DRUMS OR ROTOR CONVERT KINETIC ENERGY INTO THERMAL ENERGY VIA
FRICTION.
THUS BRAKES ARE ESSENTIALLY A
MECHANISM TO CHANGE ENERGY
TYPES
4. TYPES OF BRAKES
MECHANICAL BRAKES
• DRUM BRAKES
• DISC BRAKES
HYDRAULIC BRAKES
POWER BRAKES
• AIR BRAKES
• AIR HYDRAULIC BRAKES
• VACCUM BRAKES
• ELECTRIC BRAKES
6. HYDRAULIC BRAKES
Hydraulics is the use of a liquid under pressure to
transfer force or motion, or to increase an
applied force.
The pressure on a liquid is called HYRAULIC
PRESSURE.
And the brakes which are operated by means
of hydraulic pressure are called HYDRAULIC
BRAKES.
These brakes are based on the principle of
Pascal’s law.
7. PASCAL’S LAW
The pressure exerted
anywhere in a mass of
confined liquid is transmitted
undiminished in all directions
throughout the liquid.
Applied in hydraulic lifts,
hydraulic brakes etc.
8. MASTER CYLINDER IN ACTION
When we press the brake pedal, it pushes on primary
piston through a linkage.
Pressure is built in the cylinder and the lines as the brake
pedal is depressed further.
The pressure between the primary and secondary
piston forces the secondary piston to compress the fluid
in its circuit.
If the brakes are operating properly, the pressure wll be
same in both the circuits.
If there is a leak in one of the circuits, that circuit will not
be able to maintain pressure.
10. USE OF LIQUIDS INSTEAD OF GASES
Liquids are used in hydraulic systems because liquids
are incompressible.
If we use a gas, on increasing the pressure, the gas will
be compressed into a smaller volume due to which
there will be no transmission of force or motion.
11. ADVANTAGES OF HYDRAULIC BRAKES
Equal braking effort to all the four wheels
Less rate of wear (due to absence of joints compared to
mechanical brakes)
Force multiplication (or divisions) very easily just by changing
the size of one piston and cylinder relative to other.
12. DISADVANTAGES OF HYDRAULIC BRAKES
Even slight leakage of air into the breaking system
makes it useless.
The brake shoes are liable to get ruined if the brake
fluid leaks out.
13. DISC BRAKES
In a disc brake, the fluid from the
master cylinder is forced into a
caliper where it presses against a
piston.
The piston in turn squeezes two
brake pads against the disc (rotor),
which is attached to wheel, forcing
it to slow down or stop.
14.
15. DISC BRAKE AND BRAKE OF A BICYCLE
Similar to a bicycle brake where two rubber pads run against
the wheel rim creating friction.
But in a disc brake, the brake pads squeeze the rotor instead
of the wheel, and the force is transmitted hydraulically
instead of through a cable.
16. DRUM BRAKES
The drum brake has a metal
brake drum that encloses the
brake assembly at each
wheel.
Two curved brake shoes
expand outward to slow or
stop the drum which rotates
with the wheel.
17. WORKING OF DRUM BRAKES
Drum brakes work on the same principle as the
disc brakes.
Shoes press against a rotating surface.
In this system that surface is called a drum.
Drum brake also has an adjuster mechanism, an
emergency brake mechanism and lots of springs.
The shoes are pulled away from the drum by the
springs when the brakes are released.
18. DRUM BRAKE ADJUSTER
For the drum brakes to function correctly, the
brake shoes must remain close to drum without
touching it.
If they get too far away from the drum (as the
shoes wear down), the piston will require more
fluid to travel that distance and the brake
pedal will sink closer to the floor when we apply
brakes.
That is why most drum brakes have an
automatic adjuster.
22. SOME MORE POINTS
Most modern cars have disc brakes on front wheels and drum brakes on
rear wheels and some wheels have disc brakes on all four wheels.
To increase safety, most modern car brake systems are broken into two
circuits, with two wheels on each circuit.
If a fluid leak occurs in one circuit, only two of the wheels will loose their
brakes and the car will still be able to stop when we press the break pedal.
23. EMERGENCY BRAKES
In cars with disc brakes on all four wheels, an
emergency brake has to be actuated by a
separate mechanism than the primary brakes in
case of a total primary break failure.
Most cars use a cable to actuate the emergency
brake.
Some cars with four wheel disc breaks have a
separate drum brake integrated into the hub of
the rear wheels.
This drum brake is only for emergency break
system, an is actuated only by the cable. It has no
hydraulics.
24. BRAKE FLUIDS
One of the important characteristics of brake
fluid is its BOILING POINT. Hydraulic systems rely
on incompressible fluid to transmit force.
Liquids are generally incompressible while
gases are compressible.
If the break fluid boils (becomes a gas), it will
loose most of its ability to transmit force.
This may partially or completely disable he
brakes.
25. TYPES OF BRAKE FLUIDS
FLUIDS
GLYCOL BASED
(ABSORB
WATER)
DOT 3
DOT 4
SILICON BASED
(DOESN’T
ABSORB WATER)
DOT 5
26. PRECAUTIONS
As a DOT 3 or DOT 4 brake fluid absorbs water, its boiling point decreases. It
can absorb water from air, that is why we should avoid opening the car’s
brake fluid reservoir and the container of the brake fluid should be tightly
sealed.
Also DOT 3 and DOT 4 brake fluids eat paint.
None of the different types of brake fluids should be mixed. They can react
badly with each other and corrode the brake system.
