You Should Know This About Your Brake Hydraulics
What Is Front Brake Hydraulics?
The
brake-pedal force is transmitted by the hydraulic braking system to the wheel
brakes through pressurized fluid. The fluid pressure would be converted into
the useful work of braking at the wheels. The brake pedal would relay the foot
effort of the driver to the master-cylinder piston, which compresses the brake
fluid. The pressure of the fluid would be equally transferred throughout the
fluid to the front disc-caliper pistons as well as to the rear wheel-cylinder
pistons. There should be a separate mechanical parking brake which should be
incorporated with at least two wheels, as per the rules. The car driver would
be allowed to stop the automobile if there are some defects in the hydraulic
brake system due to this provision.
Where Is Front Brake Hydraulics Located?
When
the brake pedal would be pressed in the hydraulic brake system, then a force
would be exerted on the piston by the pushrod in the master cylinder. This
would cause the fluid to flow into a pressure chamber from the brake fluid
reservoir through a compensating port.
Important Features Of Front Brake Hydraulics
Here
are some essential features of the
Front Brake Hydraulics:
- There
should be equal braking effort to all the four wheels
- Keep
in mind that there should be less rate of wear
- There
should be force multiplication (or divisions) very easily just by changing the
size of one piston and cylinder relative to other
How Does Front Brake Hydraulics Works?
Drum
Hydraulic Brake
Now
when the car driver would apply the brakes in a vehicle which is equipped with
drum type hydraulic brakes, then the following process would start taking
place:
- Just
because of the movement or actuation of brake pedal, the connecting rod which
is attached in between pedal as well as the piston of a master cylinder would
move, which in turn would push the master cylinder’s piston inside the master
cylinder just like a medical syringe.
- Now
because of this movement of the piston which is inside the master cylinder the
compression of brake fluid inside the master cylinder would take place, which
would provide the conversion of mechanical energy into hydraulic pressure.
- Then
the brake fluid which is highly compressed from the master cylinder would start
moving inside the brake and then the transfer of this hydraulic pressure from
master cylinder to the brake drum would start taking place.
- When
the brake fluid would start entering the wheel cylinder or drum cylinder
because of its high pressure, then the movement in the cylinder piston would start
taking place, which would then expand the stationary brake shoes which are
attached to it.
- Because
of the expansion of the brake shoes, there would be a frictional contact
between brake shoes and drum lining. It would then convert the kinetic energy of
the vehicle into heat energy and then finally the braking would start
occurring.
Single Acting Drum Type Braking
This
type of brake system works exactly in the same manner as the one which is
mentioned above. Now in this type of braking single wheel or a single pair of
wheels would get the braking force.
Double
Acting Drum Type Braking
Now
in the double acting hydraulic brake, the high-pressure brake fluid would be
distributed in 2 directions i.e. both the wheels in bikes and all wheels in
cars. This is because of the utilization of the tandem master cylinder.
Disc
Hydraulic Brakes
When
the car driver would apply brake in an automobile which is equipped with disc
type hydraulic brakes then it processes which is involved is similar as drum
hydraulic bakes up to when the high-pressure brake fluid would start entering
the brake lines but differ a bit after that:
- The
high-pressure brake fluid would start entering the disc caliper cylinder from
the brake lines of a disc brake system.
- A
movement in the caliper cylinder’s piston would be caused by the high-pressure
brake fluid which in turn would cause the movement of the brake pad which is
attached to the piston inside the caliper.
- Because
of the movement of brake pad, the clamping of the rotating disc rotor would
start taking place and because of this frictional contact between brake pads
and the rotating disc rotor, there would be a conversion of automobile’s
kinetic energy into heat energy which would in turn stop or de accelerate the
automobile.
Single Acting Disc Type Braking
The
single acting disc type hydraulic braking works exactly in the same manner as
the one which is mentioned above. Now in this type of braking single wheel or a
single pair of wheels would get the braking force.
Double
Acting Disc Type Braking
Now
in the double acting disc type hydraulic brake, the high-pressure brake fluid
would be distributed in 2 directions i.e. both the wheels in bikes and all
wheels in cars. This is because of the utilization of the tandem master
cylinder.
Frequent Problems with Front Brake Hydraulics
There
can be a lot of causes of the front brake hydraulics failure in automobiles.
Disc brakes with hydraulic system are used by the conventional passenger car,
so the issues with those components can cause failure in the brake. The most
common cause due to which a failure in the hydraulic system can be caused is
the air which gets trapped in the hydraulic pipe line for the brake.
