3. What are brakes? A mechanical device Prevents motion of moving body

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

5. * 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

6. * Types Of Brakes Disk Brakes Drum Brakes Vacuum Brakes Air Brakes Hydraulic Brakes Railway Brakes

7. * 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.

8. * Construction of disk brake

9. * 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

10. * Construction of drum brake

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

12. * Construction

13. * 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

14. * Construction

15. * 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.
