B:
BALL JOINTS: a movable joint ffound on the steering linkage and suspension system of the car that permits rotating movement in any direction between the parts that are joined.

BEARINGS: anti-friction devices that are usually found between two moving parts to help movement while preventing wear. bearing are found in balls or roller types.

BLEEDING A SYSTEM: to remove air bubbles from a brake system. fuel injection system, or a cooling system so that they don't impede the flow of liquid throuh that system.

BORE: the width or diameter of a cylender hole where gas is burned and pistons are pushed.

BOXER ENGINE: aka flate engine, 180 degree V engine, its an internal combustion engine with pistons that are all relatively horizontal. its was invented and used first by the german engineer karl benz 1896.

BRAKE BOOSTER: if your car has power brakes, a brake booster is located between the brake pedal and the master cylender to increase the force applied to the brakes.

BRAKE CALIPERS: the clamp like device or disk brake system that sqeezes the brake pads onto the brake disc to slow down or stop the car.

BRAKE DISCS: also known as rotors. these are used universally on front braking systems and on some rear braking systems. brake fluid under pressure pushes pistons in brake calipers. which clamp a set of brake pads around one corner of the rotating disc and slow it down .thus slowing down the car.

BRAKE DRUMS: part of the braking system, these are metal drums mounted at the rear wheels on some cars. the brake shoes press against the inner suface of drum to slow or stop the car.

BRAKE FLUID: liquid used in hydraulic brake system to stop or slow the car.

BRAKE LINES: a system of hoses and metal tubes through which the brake fluids flows from master cylender to the brakes at each wheel.

BRAKE LINING: for drum brakes, this is high friction and heat resistant material that's attached to a brake shoe . when the shoe is pressed against the brake drum. the lining grabs the inside of the drum. which stops the wheel and then the car.

BRAKE PADS: for disc brakes,these are friction materials on metal backing plate that,during braking,is clamped around a brake disc by brake calipers pistons to slow down the wheeel to which it is attached .

BRAKE SHOES: curved pieces of metal on which brake lining are bonded. the shoes push the lining against the brake drum in order to slow or stop the car.

BUSHING : a protective liner that provides a cushion between moving metal parts.
