A piece of rubber or plastic that fits in between two components. Bushing protects the two components from excess wear and damage.

The engine’s camshaft is driven by the crankshaft via the engine timing belt or timing chain and controls when the engine’s valves open and close. Older cars have the camshaft inside the engine, but newer vehicles have overhead cam designs

Carbon monoxide is formed when not enough oxygen is present during the combustion process to convert carbon (C) to carbon dioxide (CO 2). An increase in the carbon monoxide (CO) emission is normally accompanied by an increase in the hydrocarbon

Carburetors are what all cars had prior to fuel injection. A carburetor takes air and fuel and mixes them in the right proportion to allow a car to run smoothly and powerfully. Some cars have multiple carburetors to allow for

A fitting inside a carburetor that meters fuel into a metering circuit where it is mixed with air in the venturi.

The system which maintains the electrical charge in your vehicle’s battery. The charging system consists of the alternator, voltage regulator and battery.

A car’s chassis is like the foundation of a house – it is the basis upon which the rest of the car is constructed.

Metal tubing and rubber hoses which connects each brake caliper or wheel cylinder to the brake master cylinder.

As the main component of a braking system, the brake master cylinder takes the pressure applied to the brake pedal by the driver and distributes it evenly to all four brakes on a car.

All-Wheel Drive (AWD). Unlike four wheel drive systems, all-wheel drive is a system that drives all four wheels at all times. An all-wheel drive system has differentials which split the engine’s power to the four wheels according to which have

The shaft around which the wheels rotate.

The process of making sure a tire will not cause vibration when driving. By using a computerized machine, a technician can locate a non-balanced tire and balance it by attaching weights on the wheel rim to even out the tire’s

A joint between two parts that allows movement in any direction by the two parts. Ball joints are most often found in a vehicle’s suspension and steering systems.

A barrel is a venturi in a carburetor where air and fuel are mixed, then taken into the intake manifold and then to a cylinder. Carburetors usually have from one to four barrels, depending on the engine application.

Car batteries store and supply electrical current to a vehicle’s starting, ignition, and electrical systems.

Bearings are used to prevent wear when two moving parts are placed very close to each other.

Bleeding removes fluid from a system, such as a brake or clutch system. When a technician bleeds a brake system, the old fluid is completely removed and replaced with new fluid.

A device that uses engine vacuum or hydrualic pressure to multiply or boost the pedal effort of the driver while braking, thus adding more hydrualic pressure to the brakes for added stopping power.

A c-shaped device used with disc brakes. When a driver presses on the brake pedal, the caliper piston squeezes the brake pads against the rotor and causes the car to slow down or stop

Brake drums are drum-shaped components which contain internal brake shoes, which expand and press against the drum, when the driver presses on the brake pedal, slowing or stopping the car.
