today while breaking it feels as if the abs is coming on at breaking nr to the stop position ie light breaking , thought it was the the system testing it self , but it have done it on each stop of the day.
when a scorp do a self test do it just do it the once , then car should be back to normal? or ........... 
there is no abs light on in car , and when turn on the ignition the abs light in dash goes out with in 3 seconds as normal .

First of all when turning ignition on a static test is done if all ok to the brain the light will go out.
When you start moving a rolling test is carried out if the light comes on after this test then it is more than likely that a sensor or sensors have failed.
As you said it only does these tests once on startup move.

yes this is were im confused , while break pedal is vibrating under foot ther is no light warning coming on
and while breaking heavy the breaking is ok
its as you get closer to the stop point (ie rd junction etc) it vibrates and feel like wheels are locking up but still no abs light , what can this mean?

It proabably is a sensor, Ford dealers can run a diagnostic & tell you where the problem lies.

hi,you just had brakes looked at so it could be rust bits stuck on the sensors this will cause the sensor to send signal to abs cos it thinks the wheel is not turning thus you get the vibs up the peddle as abs is working.

The light on the dash doesn't come on when the ABS system is activated .
However, the light should stay on after start up if the ABS system is faulty
