Car Brakes
A brake is a mechanical device that stops or slows down motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion. This is accomplished by using friction. There are different types of brakes. They are as follows:
  • Electromagnetic – These brakes are often used where an electric motor is already part of the machinery. Many hybrid gasoline or electric vehicles use the electric motor as a generator to charge the car’s electric battery and also as a regenerative brake. Electromagnetic brakes slow down objects through electromagnetic induction. Electromagnetic induction creates resistance and in turn either heat or electricity. Friction brakes apply pressure on two separate objects to slow the vehicle down in a controlled manner. Related types of such a brake are eddy current brakes, and electro-mechanical brakes. These are actually magnetically driven friction brakes, but recently referred to as electromagnetic brakes as well.
  • Frictional – These brakes are commonly divided into two categories – shoe and pad brakes. It uses an explicit wear surface as well as hydrodynamic brakes, which use friction in a working fluid and do not explicitly wear out. Friction brakes are often rotating devices with a stationary pad and a rotating wear surface. There are common configurations and specifications which include shoes that contract to rub on the outside of a rotating drum, such as a band brake. The rotating drum with shoes that expand to rub the inside of a drum are commonly called a drum brake, even though other drum configurations are available as well as pads that pinch a rotating disc. These are commonly called disc brakes. A drum brake is a vehicle brake. Friction of a drum brake is caused by a set of brake shoes that press against the inner surface of a rotating drum. The drum is connected to the rotating road wheel hub. They are generally found on older cars and trucks.
  • Pumping – These brakes are often used where a pump is already part of the machinery. Some engines use a valve override, which is called a Jake brake, to greatly increase pumping losses. These pumping brakes can dump energy as heat, or can be regenerative brakes that recharge a pressure reservoir which is also known as a hydraulic accumulator.

You may think that the drum brake is a little complicated and maybe quite intimidating when open, but don’t fret, we’ll break it down for you…. (Break – brake… get it?) Drum brakes are named because of the round drum that comprises part of the wheel housing. Although open from the backside, from the front the large cylinder resembles a drum. Like the disc brake, the drum brake has two brake shoes and a piston. But the drum brake also has an adjuster mechanism, an emergency brake mechanism and lots of springs. They are similar to disc brakes in the fact that they are designed to help the vehicle stop quickly and safely. They have several features that make them unique. There are many components to a drum braking systems, namely:
  1. Backing Plate
  2. Brake Drum
  3. Wheel Cylinder
  4. Brake Shoe
  5. Automatic Adjuster
Now that we know the components, let’s find out how they work together. The driver applies pressure to the brake pedal inside the vehicle, which sends hydraulic pressure from the master cylinder to the pistons. The master cylinder is the main component of the braking system and is different from the wheel cylinder which operates only one brake.   The pistons are pushed towards the shoes, which presses them against the drum. This forces the vehicle to stop. When the driver removes his or her foot from the brake pedal, the springs cause the shoes to go back into place. They do not move very far away unless the components are worn. When this happens, the driver will have to press the brakes down farther to release enough fluid to travel to the pistons. Drum brakes do get worn down over time, therefore it is quite important to replace them when it is required. Advantages of using drum brakes:
  • Low Drag
  • Drum brakes cost less to manufacture therefore are cheaper to purchase
  • The maintenance is easier
  • You can use them with disc brakes
