Many aftermarket parts are made by the same companies that supply the original equipment part to the vehicle manufacturer.  \nAll-wheel drive (AWD): A permanent, four-wheel drive system designed for improved traction on all surfaces and at all times. The main difference between AWD and 4WD systems is that the driver cannot disengage AWD.  \nAnti-freeze (coolant): The liquid in the engine cooling system that dissipates heat. Engine coolant prevents freeze-up in winter, raises the boiling point in summer, and protects the cooling system from rust and corrosion year round.  \nAnti-lock braking system (ABS): System that prevents wheel lock-up by automatically regulating the brakes. ABS can decrease braking distances on slippery pavement , prevent skidding and provide greater control during sudden stops.  \nAxle shaft: On front-wheel drive vehicles, the shafts that connect the transaxle to the driven wheels. Axle shafts are also used on some rear-wheel drive vehicles with independent suspensions to connect the differential assembly to the driven wheels. Axle shafts commonly have a universal joint at each end to accommodate suspension movement. In front-wheel drive applications, constant velocity joints are used that smooth power delivery and allow the wheels to be turned for steering.  \nBackfire: Gunshot-like sound from the engine air intake or tailpipe.  \nBalancing (tires) : Adding small amounts of weight to a wheel to offset any imbalance present in the tire and wheel assembly. Proper balance eliminates wheel and tire vibrations that are annoying, can reduce traction in certain circumstances and cause increased tire and suspension wear.  \nBattery: The component that stores the electrical power needed to start the engine. The battery also powers vehicle accessories when there is insufficient power output from the charging system, and acts as a “shock absorber” for the vehicle electrical system.  \nBattery acid (electrolyte): The fluid in automotive batteries, a mixture of sulfuric acid and water.  \nBattery hold-down: A fastening device used to secure the battery firmly in place. The two most common types are the wedge, which clamps over a protrusion near the bottom of the battery, and the bracket , which fits around or across the top of the battery and is secured with long threaded rods.  \nBottoming: When your vehicle reaches the limits of the suspension travel (such as when going over bumps), and the vehicle’s springs are completely compressed. This results in a sudden transfer of  \nnoise/harshness, particularly through the steering, and possible contact of the vehicle undercarriage with the pavement.  \nBrake booster: A vacuum or hydraulic powered device that multiplies the foot pressure applied to the brake pedal to increase braking power while reducing the required driver effort.  \nBrake caliper: The hydraulic assembly that contains the brake pads and applies them against the brake rotor to slow or stop the car.  \nBrake drag: Brakes that do not completely release after application.  \nBrake fade: A loss of braking efficiency caused by high brake temperatures. Fade typically occurs during extended and/or repeated heavy brake usage. Brake fade requires increased pedal pressure to maintain the same level of braking action, and in extreme cases the brake pedal may sink to the floor causing a near total loss of braking ability.  \nBrake fluid: The liquid in the brake system that acts as a hydraulic fluid. As you step on the brake pedal, brake fluid is forced through the system to apply the brake assemblies at the wheels.  \nBrake fluid reservoir: The container that stores a supply of brake fluid until it is needed. On most vehicles, the reservoir is attached to the brake master cylinder.  \nBrake maste","cbCaiuhxBSvhbJ59","https://ap.wps.com/l/cbCaiuhxBSvhbJ59","pdf",82087,"English","[{\"question\":\"What is the difference between AWD and 4WD in this glossary?\",\"answer\":\"AWD is a permanent four-wheel drive system that improves traction at all times, and the driver cannot disengage it.
