Principles of Hydraulic Brake Systems

Energy- the ability to do work. The good thing about energy is that is can be converted to one from into another. For example you eat a bowel of cereal, All the vitamins and nutrients in that bowel of cereal, give you a lot of energy. You decided to wash you car, clean the whole house.The energy from the cereal is being transferred.

To move a vehicle it requires energy, the energy is not lost it just changes states, when gasoline is injected into the car it changes states an becomes heat energy, then the engine converts this into motion, and then various devices, such as crankshaft, transmission etc.the wheels rotate allowing the motion to move the vehicle, the longer you drive the warmer the tires get. ..this energy is in a form of heat energy.

Power- engines change potential energy of gasoline into heat energy, In relation to automobiles, power is the rate at which an engine changes energy of the gasoline into heat energy, So the engine that causes energy change states, so it can move and power the vehicle, which would be called POWERFUL.

FRICTION- friction is the resistance to motion between two objects in contact with each other. if you rub your hands together very fast, you will change the kinetic energy of you removing hands into heat energy. This change occurs because of the friction that exists between the surface of your hands. brake systems use friction to slow down, stop and to hold the wheels of the vehicle. when a vehicles is moving it has a massive amount of stored energy, called inertia. In order to stop a vehicle, the brake system uses friction to convert the kinetic energy into heat..

traction- just as the brake shoes and drums require friction to slow or stop the rotation of tires, the tires also require friction to slow or stop the momentum of the vehicle. The ability to supply this kind of friction is called traction. No matter how well the brakes stop the rotation of he tires,if the tires do not supply traction the vehicle will not stop

tires- the type of tires has an effect on the braking system. the concern of the type of tire is not as important as the condition of the tire being used. it is extremely important to use the recommendation from the manufactures of the vehicles. tires should always be inflated in order to attain the highest coefficient of friction without sacrificing safety. This results in good traction, effective braking also helps gas mileage.

weight and balance- these are a couple more requirements in order to stop your vehicle. There must be balance between the brake force sent to the wheels from side to side, and from front to rear. If brake force is not balance it could cause the wheel to lock up, which would also result in a skid.
