2008 escape , on dry ground under mild braking , pedal pulsates and abs light just came on

high speed and heavy braking will produce a pulsation in the pedal
that is the abs working properly and the pulsations are the brake release and reapplying
intermittent abs light indicates a wire or wheel sensor problem at one of the wheels

ABS system has nothing to do with base brake operation . ABS light on ? There are DTC'S - diagnostic trouble codes ,have codes checked ! No it's not a ground issue .

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.

you could try the abs pump itself try getting one from a breakers yard
hope this helps

bleed the brakes again starting form the longest line back to the shortest
if you have been getting a pulsing feeling at the pedal under normal brakes you have warped rotors that need replacing or machining
under normal brakes the abs is not effective and it is only under sever brakes that you will experience the pulsations at the pedal

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.

The pulsation is normal and caused by the antilock brake system, any time the brakes are applied rapidly the abs will kick in and you will feel pulsations in the pedal.

Hi,

If you have ABS on this vehicle which these models do, the brakes will ulsate if the pedal is depressed quite hard.

It does this because the ABS is working and it does make the brake pedal feel like its vibrating.

Hope this helps

Thanks

worn out pads or rotor, possible broken abs cable to brake. first check to see if all 4 are connected. all ore on back side of brake dust shield. than check to see if the brakes are worn last is the rotors. also see if there is a recall on the brake and battery re charge system.

Or you could just pull the fuse for the abs and not have abs but you won't wreck from pulsating pedal.
