Anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking http://www.cheapairmax270freeshipping.com/ , preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than a driver could manage.

ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, ABS can significantly increase braking distance, although still improving vehicle control.


Types Of ABS Brakes:


脗 Anti-lock braking systems use different schemes depending on the type of brakes in use. They can be differentiated by the number of channels: that is, how many valves that are individually controlled and the number of speed sensors.


Four-channel cheap air max 720 , Four-Sensor ABS


This is the best scheme. There is a speed sensor on all four wheels and a separate valve for all four wheels. With this setup, the controller monitors each wheel individually to make sure it is achieving maximum braking force.


Three-channel, Four-Sensor ABS


There is a speed sensor on all four wheels and a separate valve for each of the front wheels, but only one valve for both of the rear wheels. Older vehicles with four-wheel ABS usually use this type.


Three-channel, Three-Sensor ABS


This scheme cheap air max 270 , commonly found on pickup trucks with four-wheel ABS, has a speed sensor and a valve for each of the front wheels, with one valve and one sensor for both rear wheels. The speed sensor for the rear wheels is located in the rear axle. This system provides individual control of the front wheels, so they can both achieve maximum braking force. The rear wheels, however cheap air max 95 , are monitored together; they both have to start to lock up before the ABS will activate on the rear. With this system, it is possible that one of the rear wheels will lock during a stop, reducing brake effectiveness. This system is easy to identify, as there are no individual speed sensors for the rear wheels.


Two-channel, four sensor ABS


This system cheap air max 97 , commonly found on passenger cars from the late ’80s through early 2000s (before government mandated stability control), uses a speed sensor at each wheel, with one control valve each for the front and rear wheels as a pair. If the speed sensor detect lock up at any individual wheel, the control module pulses the valve for both wheels on that end of the car.


One-channel, one-sensor ABS


This system is commonly found on pickup trucks with rear-wheel ABS. It has one valve cheap air max 90 , which controls both rear wheels, and one speed sensor, located in the rear axle. This system operates the same as the rear end of a three-channel system. The rear wheels are monitored together and they both have to start to lock up before the ABS kicks in. In this system it is also possible that one of the rear wheels will lock, reducing brake effectiveness. This system is also easy to identify, as there are no individual speed sensors for any of the wheels.

Know when to send in your Press Release
Copyright ? 2006




Press releases should target either general interest or
special interest media. Your targets should include print,
broadcast, and internet media. General interest media
includes your local newspaper cheap air max shoes , Time magazine, and some
of your local radio and television stations.


Special Interest media includes trade publications and
broadcast media that focuses on some niche area of interest.
The important thing to remember as you pursue this avenue,
is that your press release must be newsworthy, ie..., news cheap nike air max ,
if it is going to be published and generate the traffic
to your website that you are seeking. You should also
recognize that what's news to one organization isn't
necessarily news to another.


Your local newspaper, the Little Ville Beacon, may think
your having a website on the internet is big news. After
all, nobody at the paper has browsed the internet themselves
yet and they don't know anyone else who has a website. So
by all means send a press release to the home town
newspaper.


Time magazine, on the other hand may not be so impressed.
They may not have actually browsed the web cheap air max , but someone
met somebody sometime at a cocktail party in Manhattan who
did. So its not news. Yet if you have the right kind of
site you might get into Time. How? Well, if it's a special
interest site it might correspond to a special interest
section of the publication or be involved in a special
event of the time.


For example, the periodical has a section that covers
politics and your website is the be all of all times
on politics. Or you might get lucky and send them your
