Hi everyone,
I`ve just been away for the weekend in my ZX, and had at one time the brakes
go VERY squishy.  Basically I pushed the pedal to the floor and there was no
resistance, nor was there any slowing down of the car.  I pumped the brakes
a few times, and they worked fine (at this point the car had stopped, it was
rolling to a halt after going up and down two fairly big passes).

Any ideas what this might have been?  The brakes worked fine after the
pumping, the fluid looks ok (according to a mechanic friend) and is the
right level.  If it makes any difference, the brake discs where changed
today, and one of them snapped where the disc joins the part that goes on
the hub (not sure of the terms, the smaller circle that in the middle).  It
snapped while it was being taken off, it had stuck on.

Thanks in advance for any help!
