I have a 97 Econoline E-150. The ABS light comes on intermittently - sometimes not for a day or two.

Last night, while stopping at a stop sign, the car lurched forward a few feet, as if the brakes had failed or faded, then the ABS light came on.

Brakes work good whether light is on or not, but it is worrying. Both rotors were recently replaced. Could something have been damaged or incorrectly assembled?

Any ideas?

Possibly need bleeding? Or is total brake failure imminent?

Thanks

e series abs equpped fords can have that issue, i dont know how to fix it, but i think it's caused by a faulty sensor. prob damaged somehow in the replacing of the discs(which have the tone wheel on the inside, which the sensor reads off.

i'm gonna try unpluging the sensors and seeing ifthat disables the abs all together. better than having an uncontrollable car for 3 metres at a stop sign.

with brake troubles... don't stuff around .. do something about it immediately. If they do fail it will always be at the worst possible time.

I have a Tarago with ABS and have found when I approach a particular set of traffic lights the van "lurchs" forward, there is a rough patch in the road before the lights, I am told the lurching is the ABS relieving the braking because it thinks it has lost traction due to the bumpy road. As soon as I pass the bumps the brakes grab again. Your light coming on sounds a worry though, best to get it checked.

This sounds a little strange, because your ABS sensors measure wheel speed, not vibration or anything like that. For the ABS computer to think you have lost traction on one of the wheels, its speed would have to be faster than the opposite wheel. Something that a dodgy road surface should not cause...

i think its faulty wiring on/to the sensors, and the bumps trigger the faults.

my abs seems to fault at the same intersections all the time. theres one right hand turn where 4 out of five times it always falses a brake lockup and after taking the corner, the abs light comes on.
