So heres my dilema, when i slam on the brakes to make a hard stop, the pedal goes down further than it should, there is a lite pulsing in the pedal and i hear a lite grinding sound.... i first noticed this back in September as I was leaving downtown Chicago on the expressway someone whipped in front of me and i had to slam on the brakes...(they didn't seem to lock up)
haven't had to stop that hard since then, until the other morning when the roads were covered in ice, and then i know the wheels were locked up, at least the fronts...same symptoms....
Is my abs failing??? the fact they locked up would suggest so... when this does occur the pedal feels as though the car is turned off and i'm stopping manually...
otherwise during normal braking everything is fine... the car stops nice and smoothly.
and yes the rotors and pads are all good
Any suggestions???
