BRAKE SYSTEM IN TRACTOR

2. BRAKE
A mechanical device
Prevents motion of
moving body

3. Principle of operation
Brake works on the
Principle of friction.

19. Hydraulic brake
HYDRAULIC PRINCIPLES:
•Fluids cannot be compressed.
•Fluids can transmit Movement.
•Acts “Like a steel rod” in a
closed Container.
•Master cylinder transmits fluid
to wheel cylinder or caliper
piston bore.
•Fluids can transmit and
increase force.

20. HYDRAULIC BRAKE SYSTEM

21. Construction
The main components of the system is
1.Master Cylinder
2.Wheel Cylinder

22. MASTER CYLINDER
Heart of the hydraulic brake system.

23. Wheel Cylinder
Second important Part in the hydraulic brake system.

26. BRAKE FLUID
•Use the one recommended by the manufacturer.
•DOT3 glycol based
•DOT4 glycol based
•DOT5 silicon based
Properties
•Low Freezing Point
•High Boiling point
•Must lubricate internal parts
•Must not evaporate easily
Brake parts can be cleaned
with brake fluid.
