Q:What is the meaning of wheel lock?

The vehicle in the use of the brakes suddenly locked, the brake does not return.This is the brake cylinder rust or stuck, you need to remove the pump cleaning or replacement.

Q:What is the difference between front wheel drive, rear wheel drive, and four wheel drive? Which kind of drive do most cars today use?

Rear wheel drive is where your rear wheels move your vehicle. Front wheel drive is where your front wheels move your vehicle. 4Wheel drive is where all four wheels move your vehicle. Which is better depends on the driver. There are arguments either way. The best way to determine for yourself is to test drive them. I'm happy with rear wheel drive, though tests have shown front wheel drive to be safer. If your tires are in good condition and not the problem you can still look into better tires that help prevent skiding. Here is pedia's technical description and link below: Front-wheel drive is the most common form of engine/transmission layout used in modern passenger cars, where the engine drives the front wheels. Most front-wheel drive vehicles today feature transverse engine mounting, where as in past decades engines were mostly positioned longitudinally instead. Rear-wheel drive was the traditional standard and is still widely used in luxury cars, most sport cars, and trucks. Four-wheel drive is also sometimes used. The vast majority of rear wheel drive vehicles use a longitudinally-mounted engine in the front of the vehicle, driving the rear wheels via a driveshaft linked via a differential between the rear axles. Some FR layout vehicles place the transmission at the rear, though most attach it to the engine at the front. Rear wheel drive has fallen out of favor in passenger cars since the 1980s[citation needed], due in part to higher manufacturing costs, and that front wheel drive is safer to drive[1], and that it performs better on slippery roads.[2][3] However, some automobile brands, including Cadillac, Mercedes-Benz, BMW and Porsche continue to use rear wheel drive platforms. Rear wheel drive (or all-wheel drive) is still the preferred choice for high performance automobiles.[4]

Wheel Sizes For Cars

Q:How to desing a car wheel?

Obvious considerations: strength, standard size, aesthetics, materials, manufacturing cost

Q:i have a 1968 mustang with magnesium alloy wheels is it true they are flammable or is that a myth

magnesium alloy will burn until it has no more to burn.I.E. it has to have the 3 sources for a fire.... heat,oxygen, and a combustible material. mag alloy has all three as when it is manufactured is has trapped oxygen in the make up, magnesium is combustible even if not in a powder source, and last heat if enough heat is built up it can burn, once it starts it is extremely difficult to extinguish. depending on the amount of time it has burned it may be impossible to extinguish even with chemicals. here is the most important thing to remember. a mag alloy on fire creates an enormous amount of heat and using water may cause the alloy explode. do not use any source that is cold to it, death will occur.

Q:i have recreational skates but its just i want to change the wheels to inline hockey skate wheels. they are size 80mm. i was just wondering are all roller skate wheels the same size as in are they thicker or skinnier??

first you should look at all your wheels. for roller hockey skates (yes, there is a special kind) there are usually different sizes between the back 2 and front 2. wheel sizes also differentiate between skates, so you must be cautious of that. they are sold in many sizes, the best places to buy them being at sport authority or online. make sure you know the correct size, tho, because they are expensive.

Q:how to adjust micras steering wheel because it stucks into the legs.thnx in advance

The steering wheel will pop up when the lock lever is pulled forth (on the down-left side of steering wheel ). Keep holding the lock lever and adjust the steering wheel to the desired position Release the lock lever to lock the steering wheel.

Q:When driving i get a whining noise from the driver side sounds like the wheel any ideas. 2001 stratus

You should generally use both brakes. 90% of the stopping 'power' comes from the front wheel. (Front wheels have 2 disc brakes!) If you only had the rear brakes, you would be severely limited in your braking ability.

Q:Why the speed of the wheel after the speed looks like a backward turn?

Not very understand, but it involves the camera frame number, initiate it. For example, the side of the tire has a large white LOGO, the camera frame number 30 frames, equivalent to 30 photos per second, and when the tire speed caused by the 30 photos of each tire that white LOGO are in the The same position, it looks like the tires are not turning the same.
