Prevents motion of moving
body

3. • Where is it used?
Wheeled vehicles like cars, planes etc.
Shopping carts
Cycles
Almost everywhere……

4. *Working of A Brake
• Functions via forced delivered to a rotating body
• Assembly with a mechanical clutch
• Tightened or pressed with body to decelarate
• Generate intense heat and some noise

5. *Types Of Brakes
•Disk Brakes
•Drum Brakes
•Vacuum Brakes
•Air Brakes
•Hydraulic Brakes
•Railway Brakes

6. *Disk brake
• Uses calipers to squeeze pairs of pads against a
disk
• Single piston floating caliper mainly used
• Main braking system in cars
• Used for instant breaking
• Used in cars, cycles , bikes etc.

7. *Construction of disk brake

8. *Drum Brakes
• Works on the principle of disk break
• Less expensive to manufacturer
• More spare parts used
• Useful in emergency breaking system
• Located on the rear wheels
• Mainly used in vehicles

9. *Construction of drum brake

10. *Hydraulic Braking
*Uses brake fluid
* Containing ethylene glycol, to transfer
pressure to braking system
*Mainly used in passenger vehicles , cars
etc.

11. *Construction

12. *Vacuum Breaking
• The vacuum in the brake pipe is created
• Maintained by a motor-driven exhauster
• Exhauster has 2 speeds
Low speed
High speed
• Specially used in trains

13. *Construction

14. *Air Brakes
• Uses air to apply brakes
• Breaks are disengaged when the air tanks are full
• Air fills the brake chamber, pushing the chamber
diaphragm
• Pushes the brake pads against the brake drum,
stopping the vehicle
• Used for heavier vehicles like in trucks ,aircraft etc.
