It is one
of the most uses full braking system.it is called hydraulic braking system
because the force is applied by the liquid pressure.
SYTEM IS USED DUHYDRAULIC BRAKINGE TO
- .For equal braking effort hydraulic braking system we us
- .Easy to construct due to absence of brake rod
- .The rate of wear is less
CONSTRUCTION
The main
component of hydraulic braking system is
- .master cylinder
- . wheel cylinder
Master cylinder is a cylinder which contains reservoir for brake fluid ,.
Master cylinder is operated by brake pedal
and connected to wheel cylinder of each wheel through the steel pipe
lines.
The system
is filled with the liquid under low
pressure when brakes are not applied .the liquid is known as brake fluid and usually mixture of glycerin ,alcohol and
some additives.
Each wheel brake consist a cylinder brake i.e
drum or disc which is mounted inside the wheel.
WORKING PRINCIPLE
Hydraulic braking system works on principle of friction.
master cylinder basically piston cylinder
device contains brake fluid .
When brake pedal is applied push rod moves the
inside the cylinder which build up a pressure .
Due to this
pressure hydraulic fluid is forced
inside the pipe lines under
pressure.
Then this
fluid enters to the wheel where as a
small piston cylinder arrangement called caliper. this high pressure oil
push the piston pads towards the drum
/disk .three by brake is applied.
