Disk brake

Usescalipersto 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

Containingethylene glycol, to transfer pressureto 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.
