Hydraulic brakes: Basics, Principle, Working, Advantages and Disadvantages
The brakes or the system of braking mechanism which are operated and applied by liquid or oil pressure from controlling mechanism to braking mechanism in order to slow down or completely stop the vehicle is known as hydraulic brakes. In simple language, hydraulic brakes are brakes which uses oil pressure for braking action. Main parts of hydraulic brakes: The main parts of hydraulic brakes are: 1) Master cylinder: The master cylinder, also known as the master brake cylinder, converts the pressure on the brake pedal to hydraulic pressure by feeding brake fluid into the brake circuit and controlling this according to the mechanical force. Disc and drum brakes, both uses…

Air brakes: Basics, Components, Working
What are Air Brakes? Air brake system is a type of braking system which uses compressed air to apply the pressure in order to stop the vehicle. Air brakes are also known as pneumatic brakes. The first air brake was invented by George Westinghouse, he introduced this type of brake for the use in trains. Air brakes are widely used in heavy vehicles like trucks and buses because they are heavy in weight and they need more effort on brake pedal to stop them, and for comfortably braking them air brake is good as it has high potential energy and does not requires much effort to push the brake pedal.…

Drum Brakes : Basics, Working, Advantages and Disadvantages
Fig: Drum Brakes Basics of Drum Brakes: Drum brakes is a type of mechanical braking system that uses friction caused by a set of shoes( a.k.a brake shoe) that presses outwards against a rotating brake drum. The braking action is caused inside of a brake drum thus, giving it a name ‘Drum Brake’. They need regular adjustment of brake wire, brake lever adjustment and requires frequent changing of shoes at a particular period of time after usage. However, these brakes are generally operated with mechanical force by brake pedals but in some other applications they were also operated by hydraulic force mechanism. However, Drum Brakes are only used in low…

Disc Brake: Basics, Main Parts, Advantages, Disadvantages and Preference
Fig: Disc Brake of Bike Basics of Disc Brake: A disc brake is a type of braking system in automobiles that uses calipers to squeeze pairs of brake pads against the rotor/disc to create friction and reduce the motion of vehicle or to completely stop it. When braking action occurs the kinetic energy is directly converted into heat energy and heat is directly dissipated to the atmosphere. The disc braking system works on the principle of pascal law according to which “ the confined liquid transmits pressure without loss equally in all directions.” In disc brake system energy is transfer from pedal to the brakes. It is also a type…
