The ABS Active monitor comes on when one or more of the wheels are not spinning at the same rate of speed. The ABS system determines wheel "lock up" from the wheel speed sensors and will adjust brake pressure to unlock the skidding wheel(s). It achieves this operation with a pump which will rapidly pump the brakes to the specified wheel. I'm assuming this is the "pulsation" you are experiencing. If you are having this problem under light to moderate braking, be sure to have the proper size tires on all 4 wheels. Incorrect tire sizes and uneven tire wear will give improper wheel speed information the the ABS controller. This will result in a malfunction of the system.

My abs light keeps turning on and off and sometimes when stopping under 5 miles an hr the break petal will pulsate i have a chevy tahoe


You didn't list the year, but false ABS activation is usually caused by dirt or metal particles on the wheel speed sensor. Read the post below to find causes for ABS lights

One more problem. My Nissan Fuga vibrates when I step on the brake pedal at high speed. Does this mean I have worn out brake pads/disks?


not necessarily
if you have abs brakes it is the pulsations as the wheels lock and unlock from the abs activity
this transmits as a pulsation under your foot
it may also mean that the discs have warped and the warp is pushing the piston back in then letting the piston out
it is more noticeable at low speed light pressure stops but it depends on the speed
Take the vehicle to an accredited brake shop specialist and get a proper diagnosis done

Breaks on Saab 2001


Did you replace the front and rear or just the front? Rear brakes can make the pulsation as well. Also if your ABS system is activating that could be described as a "pulsation". The ABS problem is usually caused by a bad wheel speed sensor or ABS module failure. ABS modules can be rebuilt (see ebay BBA-Reman) Wheel speed sensors are available at most auto parts stores. Some Saabs require the replacement of the whole hub assembly.

2005 Chevy impala brake pedal pulsation with brand new rotors installed


Is your ABS working properly? Under heavy braking the ABS should engage and 'pulse' the brakes on/off. It is normal to feel the brake petal flutter or pulse under your foot.

Under light braking there should be no pulsing as the ABS does not engage and you have changed the rotors and pads.

ABS, TRAC OFF, SERVICE VEHICLE SOON LIGHTS ARE ON. BRAKE PEDAL PULSATES INTERMITTENLY AND MAKES NOISE.


with these lights on then you will have to see what codes are in the abs and pcm module to find out what the problems are.the abs module will activate when the traction control lights come on.this can also cause a noise and pulsate in the brakes pedal.

Brake pulsating and abs light is on


brake pulsation is caused by warped brake rotors, not sure the ABS light and the pulsation are related, The ABS warning light requires a scanner to be connected and to read the fault code that is stored when the ABS warning light is turned on.

I feel shaking in brake pedal of my 99 rodeo and squealing


Most likely cause is out of round brake rotors.
They will need to be resurfaced or replaced to correct the pulsation you feel in the pedal.
One other cause I can think of is the ABS (anti lock brake system) is activating due to possibly a bad wheel speed sensor.
You can disconnect the power connector at the ABS control unit and road test the vehicle.
If the pulsation is still there than it is not an ABS problem.

Anti lock brake system


If the light is not on it may not be the ABS that is pulsating on slow braking but it may be that your have warped brake rotors, even if the rotors were replaced with the pads the new ones may be warped already, we always check new rotors on a brake lathe before installing them because we have seen this happen many times

Brakes pulsate real hard


That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.
