A brake is a mechanical device that slows or stops motion by absorbing energy, primarily through friction. There are several types of brakes, including frictional brakes (such as shoe and pad brakes), pumping brakes that utilize engine losses, and electromagnetic brakes that apply mechanical resistance through electromagnetic force. Each type of brake serves different functions and applications in vehicles and machinery.

1. BRAKES

2. What is BRAKE?
A brake is a mechanical
device that inhibits motion by
absorbing energy from a moving
system.

3. PURPOSE
For slowing or stopping a
moving vehicle, wheel, axle,
or to prevent its motion, most
often accomplished by means
of friction.

4. TYPES
FRICTIONAL BRAKES
PUMPING BRAKES
ELECTROMAGNETIC
BRAKES

5. FRICTIONAL BRAKES
Frictional brakes are most common and
can be divided broadly into "shoe" or "pad"
brakes.
Shoe Brake@drum Brake
Pad Brake@disk Brake

6. Pumping brakes
 An internal-combustion piston motor can have the fuel
supply stopped, and then internal pumping losses of
the engine create some braking. Some engines use a
valve override called a Jake brake to greatly increase
pumping losses. Pumping brakes can dump energy as
heat, or can be regenerative brakes that recharge a
pressure reservoir called a hydraulic accumulator.

7. Electromagnetic brakeS
 Electromagnetic brakes (also called electro-mechanical
brakes or EM brakes) slow or stop motion
using electromagnetic force to apply mechanical
resistance (friction). Both electromagnetic brakes
and eddy current brakes use electromagnetic force but
electromagnetic brakes ultimately depend on friction and
eddy current brakes use magnetic force directly.

8. Types
 Single face brake
 Power off brake
 Particle brake
 Hysteresis power brake
 Multiple disk brake
