ABS sensor problems should not coarse brake failure as a ‘fail safe’ function must, by necessity be built
in.
If any vehicle was to suffer catastrophic brake failure whenever the exposed and sensitive sensors gave
up, it would be immediately recalled by the manufacturer.
Removing all the sensors or even just cutting all the connecting cables should leave the vehicle with fully
functional brakes with no ABS.
If Fredrik has an ABS OUT OF USE indication it should be safe to continue to drive remembering that
only the sophisticated anti block function is lost.
Will do some experiments on my Exclusive with sensors disabled.

I might be wrong but this happened to me too many times on 3 XMs!!!! My 1st XM suffered from this
problem and it was never sold. My second XM suffered from the same symptoms and was cured after 8
visits to the garage. Our company XM also had the problems and was cured immediately after changing
the front sensors. It is an electronic failure (apart from the ABS OUT OF USE warning), you can feel it.
It has nothing to do with air in the system. BTW, the XM doesn’t need any bleeding, the car will do that
itsself.
And again Harry, I know it doesn’t make any sense what I’m telling you, but believe me, when you’ve
experienced something on 3 cars, you MIGHT be right after all.
Good luck!

Disconnecting the sensors will not show the same behaviour
as what we are discussing here.
