Heh. Excellent urban myth

The only thing is, the Citroen sinks/sank to it's lowest level
anyway when

the engine is shut off.

Also the brakes and suspension ran off the same system.


Not an urban myth, actually happened, reported in the papers as I
have said. Whether those reports were accurate is another matter.
You could probably find some reference to the incident if you were
to rummage through newspaper cuttings libraries.


They ran off the same hydraulic pump, though I thought the baking system
had a separate accumulator.

On the BX's and GSA's that I had, the accumulator was shared between the
suspension and the brakes, as was the pump.

In the event of failure of the pressure system, the brakes reverted to a
standard non-servo system operated by the pedal. As you can imagine,
this was just enough to bring you to a gradual halt, especially as only
the front brakes worked in this scenario.

Some had rear brakes which had a variable pressure limit according to
the suspension are position, ie weight proportionate.

GSA's and BX's had this. It was an excellent system, as no matter nhow
much weight you put into the back of the car, the pedal pressure
required to stop or slow down hardly changed.

If a Citroen sank to the ground overnight, it needed either new spheres
or a replacement accumulator. If the pressure regulator clicked as well,
it was the accumulator. Either way, it takes a maximum of half an hour
per sphere, from putting the jack under the car to driving away. If they
aren't too far gone, the spheres can be recharged with gas for another
few months of smoothness, rinse and repeat as required.
