When driving the ABS system doe not operate. During an attempt to stop pressure on the brake pedal activates the system but it does not always do anything. Only when a wheel skids does the system turn on. A wheel that is still turning while braking is more effective at slowing the vehicle. (look up Kinetic versus Static friction) When the ABS detects a skidding wheel it pulses the pressure to each wheel in a sequence. The pulsing helps keep the wheel turning and slows the vehicle better.

What does it mean when the ABS light is on in 1999 Pathfinder?
The antilock braking system is a separate system from the regular brake system. The antilock system can go out while the service brakes work fine. If that happened, it would not affect the regular braking performance; but the anti lock feature would not function properly in a panic stop or when stopping rapidly on wet or slippery roads. The light is likely to have come on because of a defective wheel speed sensor or a problem in the electronic ABS controls. It could also indicate that the ABS fuse is blown.
What would cause the abs light on the dash to stay on all the time on a 1999 ford f150?
The ABS computer has detected a fault in the Antilock Braking System. Often it is a wheel speed detector or a modulator.
Why would the antilock brake light come on?
Antilock Brake Light comes on and stays on when the ABS computer detects some problem with the antilock brakesystem components. You will still have normal brake use, but the Antilock system will probably not work as an Antilock brake system is supposed to work. ABS system diagnostic code readers are available and are recommended for diagnostic purposes, however fixing ABS systems is perhaps best left up to the Pros. . .
Why would a 1997 Explorer Sport have pulsation during braking?
Could possibly be Antilock Brake System kicking in (most people don't notice this unless they are pressing the brakes exceptionally hard) Another possibility is that the brake rotors could be warped.
How do Antilock braking system work?
braking force is applied intermittently so the pads are pressed against the disc - then released to let the wheel turn - giving you full control. If it was a straight press and hold - the wheel would lock and you would skid, uncontrolled, to a halt. By the way this happens about 45 times a second, so technically, yes - it would be quicker to stop with a constant force, but the saftey aspect of not skidding overcomes the difference.
Does the abs light have anything to do with the check engine light?
NO, but it would be a good idea to have your Antilock Brake System checked.
Does friction effect braking force?
Most certainly for without friction the braking system would fail no matter how much force was applied.
Would bad oxygen sensor cause bas esp light to come on in 2008 magnum?
No. BAS (brake assist system) and ESP (electronic skip protection) are part of the antilock brake system. They have nothing to do with the oxygen sensors.No. BAS (brake assist system) and ESP (electronic skip protection) are part of the antilock brake system.

What is an abs modulator?
All antilock brake systems control tire slip by monitoring the relative deceleration rates of the wheels during braking. If one wheel starts to slow at a faster rate than the others, or at a faster rate than that which is programmed into the antilock control module, it indicates the wheel is starting to slip and is in danger of breaking traction and locking up. The ABS system responds by momentarily reducing hydraulic pressure to the brake on the affected wheel or wheels. Electrically operated solenoid valves are used to hold, release and reapply hydraulic pressure to the brakes. This produces a pulsating effect, which can usually be felt in the brake pedal during hard braking. You may also hear a buzzing or chattering noise from the ABS hydraulic unit. The rapid modulation of brake pressure in the brake circuit reduces the braking load on the slipping wheel and allows it to regain traction, thus preventing lockup. It is the same as pumping the brakes, except that the ABS system does it automatically for each brake circuit, and at speeds that would be humanly impossible, up to dozens of times per second depending on the system (some are faster than others). Once the rate of deceleration for the affected wheel comes back in line with the others, normal braking function and pressure resume, and antilock reverts to a passive mode.
What are some of the problems you would expect with a used Volkswagen Passat?
A few problems you would expect with a used Volkswagen Passat are problems with the fuel system, braking system, and engine.
What would cause the abs light and brake light to stay on in a 2000 Chevy Malibu?
the ABS light indicates a problem in in Abs system, a brake light indicates a problem with main braking system. such as low fluid level, leaks in system, parking brake on etc. Abs system works in conjunction to brake system. but abs system is not the main or basic braking system.
If my antilock brake system went out on a 1997 F-250 would i still have brakes?
As long as the red " BRAKE " light is not on in your dash you still have " normal " brakes even with the ABS light on
