  2.972 How Anti-Lock Brakes Work
The pressure of the hydraulic fluid in the braking cylinders is proportional to the force applied to the brake pedal by the driver.
Disc braking systems have seven main components: the wheel shaft, the rotor/disc, the caliper, its mounting, the brake cylinders, the pistons, and the brake pads.
When the brakes are engaged under normal use (the antilock braking system is not engaged), the valve is open, and the pressure in the chamber is the same as the pressure in the master cylinder.

 Anti-lock braking system - Wikipedia, the free encyclopedia
An anti-lock braking system (ABS) is a system on motor vehicles which prevents the wheels from locking while braking.
However, a limited form of anti-lock braking, utilising a valve which could adjust front to rear brakeforce distribution when a wheel locked, was fitted to the 1964 Austin 1800.
ABS brakes are the subject of some widely-cited experiments in support of risk compensation theory, which support the view that drivers adapt to the safety benefit of ABS by driving more aggressively.

Braking systems, especially antilock braking systems (ABS), are taken for granted.
With standard brakes, a slam-on-the-brakes panic stop or a short stop on a wet, slippery road may cause the wheels to lock or skid.
The antilock braking system is a computerized system, which works in coordination with wheel-speed sensors and the regular brake system on a vehicle.

 Antilock Brakes, Anti-lock Brake System
Because the rear-wheel antilock systems have only a single channel, they are much less complex and costly than their three- and four-channel, four-wheel counterparts.
On ABS systems that have a conventional master cylinder and vacuum booster for power assist, a small accumulator or pair of accumulators may be used as temporary holding reservoirs for brake fluid during the hold-release-reapply cycle.
Antilock brake systems (ABS) are used on millions of vehicles, but many drivers still don't know the "right way" to use ABS in an emergency.

 Anti-lock braking system : Antilock brake controller   (Site not responding. Last check: 2007-10-31)
An Anti-lock Braking System (commonly known as ABS) is a system on motor vehicles which prevents the wheels from locking[?] while braking.
ABS do not cause a lengthening of the braking distance on high-traction surfaces such as bitumen (even when wet): it is true that its main function is to decrease braking force on selected wheels, but it does so only to wheels that were locking, and so where not contributing effectively to the braking action.
When drivers do encounter an emergency situation that causes them to brake hard and thus encounter this pulsing for the first time, many are believed to reduce pedal pressure and thus lengthen braking distances and contributing to a higher level of accidents than the superior emergency stopping capabilities of ABS would indicate.

 Antilock brake system
With antilock brakes, all a operator needs to do is "brake and steer." With four-wheel antilock brakes, push the brake pedal hard while steering normally and keep your foot firmly on the brake pedal until the vehicle comes to a complete stop.
The mechanical noise or pulsation of antilock brakes when in use might catch an operator by surprise; however, these sensations tell you that the system is working.
Antilock brakes cannot compensate for driving too fast, too aggressively or failing to maintain a safe distance between vehicles.

The antilock braking system prevents wheels locking or skidding, no matter how hard brakes are applied, or how slippery the road surface.
An anti-lock braking system (commonly known as ABS, from the German name "Antiblockiersystem" given to it by its inventors at Bosch) is a system on motor vehicles which prevents the wheels from locking while braking.
This is particularly true of vehicles with less-sophisticated hydraulic braking systems where fine control is not as easy as with the more developed braking systems.

The electronic antilock braking four port system consists of two magnet valves (see figure) per wheel brake cylinder and two recirculation pumps with one drive.
If the difference of the number of revolutions between the wheels - while braking - is too large, the pipe to the wheel brake cylinder of the slower or locking wheel is blocked with a magnet valve.
Naturally, the reaction time of the braking system at the wheel is much too slow to perform a full standstill or a full easing of the brake in accordance with the fast pulsation.

 Bosch Braking Systems, 25 years of the Bosch ABS antilock braking system
An absolutely core component of driving safety is celebrating its 25th anniversary: the ABS antilock braking system.
The system - launched first by Bosch in 1978 - prevents a vehicle's wheels from locking under hard braking, so that the driver retains control of steering even in such extreme situations.
Since then, Bosch has continued to improve the ABS brake control system: Traction Control Systems (TCS) stop the wheels spinning under hard acceleration and the Electronic Stability Program (ESP) acts on the engine and brakes to reduce the risk of skidding in extreme situations.

 SPECIALTY AUTO ELECTRIC ABS Systems
A properly functioning ABS system is designed to prevent your car from skidding on heavy braking or braking on slippery surfaces.
Through a series of sensors, valves, pumps, relays and module the ABS system monitors the braking of each wheel (or both rear wheels on a rear wheel ABS system.) When it senses the lock-up of a wheel during skid, the ABS will automatically pulse the braking of that wheel (or wheels) to prevent skidding.
That many "brake shops" are not equipped to properly diagnose ABS problems, often resulting in an costly repair bill due to unnecessary component replacement.
