I got a abs light that wont shut off. I changed the sensor on the rear axel, break fluid full.

it will sometimes when applying breaks act like the abs is kicking on. that stuttering break feeling in the peddle. then the light shuts off then comes back on.
any ideas? 1999 f150
thanks

 

Test the front sensors too to rule them out. Use a volt/ohm meter to check for continuity on each of the fronts. lemme know if you need some more instruction on how to do so.
