My abs cuts in when I gently press the brake pedal at speeds 10-30 mph any ideas where to find fault?

This sounds like the problem caused by the rear offside wheel bearing. Arctic (Steve)has done some work on this and I think he may have traced it to corrosion on the brake back plate.

Tried to search the forum but no joy, typed in brake back plates, then under artic then both, so can someone give me a link to his posts on this fault.

HI Mick.
It will most likely be rear off side wheel bearing or corrosion from the back plate onto the sensor, first job is to make sure which one it is T4 (Testbook version 4.Computer Diagnostic System) the best way to trace the fault, after that it gets complicated.

I will be doing a post over the holiday if I have time, as your abs light come on the dash yet ?

the ABS (Antilock Braking System) light in the past has come off and on several times then worked correctly, at present the light is out with the fault, I have bought new back plates and hubs for both sides, I have bearing pullers to remove the inner race should it not release, I may have to get new ABS sensors if the fault persists, changing the parts to me is not a big deal in that changing them can only do good, however I do not know of any body in the south(Saffron Walden) that has a T4 setup to test the car at present.
I hope you do get time to do the posting as I am in the dark as to sorting the fault.
