You most likely have a wheel speed sensor dropping out this would make abs system think one wheel is locking up and therefore activate. this usually will happen rt before you stop at around 5mph or so.Also if you have bigger tires than factory and have not had abs programmed for this size it can aggravate it

Hi!
You dont have to disconnect the ABS system to replace brake pads on your vehicle, definatly. Dont forget to pump brake pressure up once your finished
Goodluck!

What is the ABS system?


the ABS is anti brake skid which is designed to stop wheel lock up under brakes and allow steering control at all times
it was originally designed for aircraft to stop the under carriage from being ripped from the plane when the wheels (under brakes on landing ) hit a wet patch , snow or ice on the runway
it works by each wheel having a segmented sender that is read by a sensor and this impulse switches on valves in the electric pump in the hydraulic system so that when the wheel stops turning ,brake pressure to that wheel is released momentarily and then reapplied when the wheel turns again
the person using the brake still feels the same brake pressure under the foot and in extreme situations will feel the brake pedal pulsate
Now the ECM continually monitors the ABS system and when fluid sensors, or electronic sensors fall outside set parameters , the ABS light comes on to let you know that there is a problem with the brakes
you should now be having the fault codes read to find the reason for the light and have it repaired as in some systems ,if the repairs are not effected then the vehicle is put into limp mode by the ECM and that reduces the power available and the speed of the vehicle.

I have a 2004 alero and when I press on the brakes to stop at a red light or stop sign a vibration occurs and it's loud but when I put it in park it stops vibrating. What can I do about this problem?


Sounds like you have warped rotors and or a lose caliper mounting bolt . When you stop do you feel a vibration in the brake peddle or in the steering wheel or both ? IF you feel the pulsation in the brake peddle I would suspect a brake pad / brake rotor problem . Now if you do not feel it in either and the vibration is through the whole car with out the brakes being applied i would think it may be related to and engine/drive line problem (motor mount /trans mount /axle problem)

I have a warning light on my dash saying there is a problem with the ABS system. Is this a safety problem?


not really. Measn that you most likely have a wheel speed sensor bad. Most often its in the front of the truck and its replaced with the wheel bearing. Although the system is disabled while the light is on the vehicle brakes are not affected

What does the abbreviation ABS mean on my Dash Board of a 1996 Nissan Frontier King Cab truck?


It stands for Anti-lock braking system, and the reason the ABS warning light is on is due to a problem with the ABS system

ABS light & trak off light keep coming on. Grinding noise & vibration can be felt on brake peddle. Brakes have been checked. Wheel bearing was replaced on drivers side. Sometimes making a pulsing...


It sounds like "False Antilock Mode" to me. Your Antilock Brake Control Module "thinks" that you have a wheel locking up. This is probably caused by a bad wheel sensor. You need to scan the module to find out which one.
