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.

4. Classification of brakes
Mechanical brakes Hydraulic brakes
Drum type
Disc type
Internal expanding External contracting
shoe type shoe type

5. Drum type
Internal expanding type of brake move by the action of a cam

6. Drum Brakes
The main components of internal expanding type of
drum brakes are
1. Brake drum
2. Brake shoes
3. Brake Liners
4. Retaining Springs
5. Cam
6. Brake Linkages

7. Internal expanding shoe type

8. DRUM BRAKE

9. External contracting shoe type
Components of External contracting shoe type brake
system
1. brake band
2.brake drum
3.brake lining
4.operating mechanism

10. External contracting shoe type

11. Disc brake

12. Disc brake

13. Disc Brakes
1.Connecting tube
2. Cylinder
3. Piston
4. Friction pad
5. Hydraulic fluid
6. Brake disc
7. From master cylinder
8. Caliper

14. WET MLTI DISC BRAKES

15. WET MULTI DISC BRAKE

16. Hydraulic Braking systems
 Hydraulic brakes make used of hydraulic pressure to
force the brake shoes.
 It works based on PASCAL’S LAW.

17. Hydraulic Braking systems

18. PASCAL'S LAW

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.

25. HYDROULIC DISC BREAK

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.
