• What are brakes?
A mechanical device
Prevents motion of moving body
• Where is it used?
Wheeled vehicles like cars, planes etc.Shopping cartsCycles
Almost everywhere……
*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
*Video of working Brake
*Types Of Brakes
•Disk Brakes•Drum Brakes•Vacuum Brakes•Air Brakes•Hydraulic Brakes•Railway Brakes
*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.
*Construction of disk brake
*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
*Construction of drum brake
*Hydraulic Braking
*Uses brake fluid
* Containing ethylene glycol, to transfer pressure to braking system
*Mainly used in passenger vehicles , cars etc.
*Construction
*Vacuum Breaking
• The vacuum in the brake pipe is created
• Maintained by a motor-driven exhauster
• Exhauster has 2 speedsLow speedHigh speed
• Specially used in trains
*Construction
*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.
*Construction
