*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.
