From previous BMW's I have owned I know the abs rarely interferes until it has to, but while bedding in my disks I have concluded that the previous owner not only didn't look after the brakes he has put hard pads and they need to be warmed up before they are any good, then they are quite good. But during my hard braking exercises (countryside empty road) not once did the abs kick despite low speed intermittent locking brakes. No lights on dash. Any thoughts?
