Brakes And Its Types

-

  Brakes are one of the most important safety features on your vehicle.  There are different types of brakes, both between vehicles and within a vehicle.  The brakes used to stop a vehicle while driving are known as the service brakes, which are either a disc and drum brake.  Vehicles also come equipped with other braking systems, including anti-lock and emergency brakes.Disc Brakes     Disc brakes consist of a disc brake rotor - which is attached to the wheel - and a caliper, which holds the disc brake pads. Hydraulic pressure from the master cylinder causes the caliper piston to clamp the disc brake rotor between the disc brake pads. This creates friction between the pads and rotor, causing your car to slow down or stop.abs Drum Brakes    Drum brakes consist of a brake drum attached to the wheel, a wheel cylinder, brake shoes, and brake return springs. Hydraulic pressure from the master cylinder causes the wheel cylinder to press the brake shoes against the brake drum. This creates friction between the shoes and drum to slow or stop your car. brake-drum Emergency Brakes     Vehicles also come equipped with a secondary braking system, known as emergency, or parking brakes.  Emergency brakes are independent of the service brakes, and are not powered by hydraulics.  Parking brakes use cables to mechanically apply the brakes (usually the rear brake). There are a few different types of emergency brakes, which include: a stick lever located between the driver and passenger seats; a pedal located to the left of the floor pedals; or a push button or handle located somewhere near the steering column. Emergency brakes are most often used as a parking brake to help keep a vehicle stationary while parked.  And, yes, they are also used in emergency situations, in case the other brake system fails!Anti-Lock Brakes

     Computer-controlled anti-lock braking systems (ABS) is an important safety feature which is equipped on most newer vehicles. When brakes are applied suddenly, ABS prevents the wheels from locking up and the tires from skidding. The system monitors the speed of each wheel and automatically pulses the brake pressure on and off rapidly on any wheels where skidding is detected. This is beneficial for driving on wet and slippery roads. ABS works with the service brakes to decrease stopping distance and increase control and stability of the vehicle during hard braking

Basic components of the engines.

Engine   is a device that produces power. It is made by various parts bolted together and they work together to achieve power by burning of fuel. These parts are given below: 1. Cylinder Block: Cylinder block or Cylinder are main part of an engine. It is a part in which combustion of fuel takes place. All other parts like piston, connecting rod, crankshaft, water jacket etc. are bolted on it. 2. Piston: Piston is placed in the cylinder and transmits thrust to the connecting rod. It is free to move. It compresses the air fuel mixture and convert the fuel energy into mechanical energy. It transmits the power to the crankshaft. 3. Cylinder Head: Cylinder head is fitted on the top of cylinder block and the function of the cylinder head is to seal the working end of cylinder and not to permit entry and exit of gases on cover head valves of the engine. The valves, spark plug, camshaft etc are fitted on it. 4. Connecting Rod: It connect piston to t

Sometimes, we wonder if technology is hurting more than helping us, and in some cases, it may be. One way that today?s technology is really helping us is by providing us with many more devices in our vehicles to keep us safe. Throughout the history of motor vehicles, there have been some significant changes. For instance, in the beginning, vehicles didn?t even have seatbelts or windshield wipers. We?ve come a long way since Henry Ford first started rolling cars off the assembly line. Today?s automobiles have all kinds of wonderful features designed to keep you and your loved ones safe. Here are 10 of the top vehicle safety devices you need to be aware of, especially when purchasing a new vehicle: 1 Airbags Some people think that these are actually dangerous, but they have in fact saved many, many lives. There are two main types of air bags, dual stage airbags and side airbags. If needed, the dual stage airbags will go off at different times, one in a minor accident and b
