Pedal goes to floor...calipers work fine .... bled brakes ...... diagnostic also.....

....then today !!!!...... Had the master brake cylinder changed cos all fault was
now pointing in this direction............NOW THEY DO NOT WORK AT ALL !!

She is now in a garage ( had to catch a lift home )
The garage is waiting for thier 'technical' dept in bmw to get back to them ....

The finger is now pointing at the 'DSC / ABS' control thingy box (part no. 34.51.6.773.013 )

So far it has cost almost £400 with no final conclusion and no X5 !!!!

To re-cap ..... pedal to the floor
................... rear brakes do not engage
................... gone through a set of front thrust arm bushes
................... calipers are not seized
................... Bled the brake system, including today, now three times
................... diagnostic shows a blank ( so cannot be electrical )
................... fitted a new Brake master cylinder...no change
....................even worse now.... pedal flat to floor and no brakes !!

............................. no car

Any ideas ?????
