could it be the brake hose or lines or fluid ?????? or some air in it ?

PLEASE HELP KNOW ONE HERE IN HOLLANDS KNOWS WHAT IT IS ? even the specialists don't know....

I'm despared ????? HELP HELP

 

It could be air in the rear lines, but you would probably have a "mushy" pedal feel if you had air in them. But try bleeding the rears and see if that helps.

Have you checked to make sure your rear brakes are in adjustment? The self adjusters might have stopped working and the shoes could simply be out of adjustment. Sounds silly, but you are looking for anything at this point.

The rear rubber brake hose between the body and the rear axle could be swollen shut and be restricting the flow of fluid to the rear brakes. I've seen it happen before.
