How Brakes Work
Explains what happens when you push on the brake pedal of a car. Includes a simple diagram of brake system components, and sections on the master cylinder, drum brakes, disc brakes, power brakes, and anti-lock brakes.

Antilock Brake Questions & Answers - NHTSA
"When used properly, an antilock brake system (ABS) is a safe and effective braking system. ABS allows the driver to maintain directional stability, control over steering, and in some situations, to reduce stopping distances during emergency braking situation, particularly on wet and slippery road surface. To gain this safety advantage, drivers must learn how to operate their ABS correctly." Basic ABS information from the National Highway Traffic Safety Administration (NHTSA).

Antilock Brake Questions & Answers (IINHS/HLDI)
"Do car antilocks reduce crashes?" No. "Why aren't car antilocks reducing crashes as expected?" One possibility: "many car owners don't know how to use antilock brakes effectively;" another: "some motorists may drive less cautiously because they believe antilocks allow them to brake better." From the Insurance Institute for Highway Safety / Highway Loss Data Institute (IINHS/HLDI)

ABCs of ABS
Check out the diagram "How the Anti-Lock Mechanism Works" and click on the links at the right: "ABS DOs and DON'Ts (do allow enough distance to stop, do practice driving with ABS; don't pump the brakes; don't forget to steer). From the ABS Education Alliance.

WHO: "World report on road traffic injury prevention"
"Road traffic injuries are a major but neglected public health challenge that requires concerted efforts for effective and sustainable prevention. Of all the systems with which people have to deal every day, road traffic systems are the most complex and the most dangerous. Worldwide, an estimated 1.2 million people are killed in road crashes each year and as many as 50 million are injured. Projections indicate that these figures will increase by about 65% over the next 20 years unless there is new commitment to prevention. Nevertheless, the tragedy behind these figures attracts less mass media attention than other, less frequent types of tragedy. The World report on road traffic injury prevention is the first major report being jointly issued by the World Health Organization (WHO) and the World Bank on this subject. It underscores their concern that unsafe road traffic systems are seriously harming global public health and development. It contends that the level of road traffic injury is unacceptable and that it is largely avoidable."
