Hi everybody
I have an N-reg xantia 1.9td and when I brake it pitches (the nose
dives up and down) a lot. The suspension also seems to be very soft. Is
this a funciton of the 'dreaded spheres' that I have just been reading
about or is there something else?

I also have the clicking sound and vibration on the brake pedal: from
my understanding I can leave it as it is only an irritation and has no
mechanical implications?
Thanks

Hi Duncan.
It sounds as though your car may have the wrong spheres fitted, as when
the spheres loose pressure this will make the ride a lot harder, but
this will not cause the pitching up and down.

How does it perform when pulling away fast ?  Do the rear mudflaps hit
the deck ? If so this could lead to the same assumption.

As for the vibration under the brake pedal, does it fell like you have
trodden on a bee ? ie buzzing slightly from under your foot, if so you
probabaly have cheap LHM. Get it out and refill the system with either
Castrol or Total LHM. In my past experience all other LHM is pants and
too thin, it works ok but the buzzing is the spool in the brake valve,
this is damped out if you use decent LHM.

Regards

I used to own a BX, which needed a darn good suspension service.
pitching, rolling, yawing, bouncing, you name it. It also failed to run
on three wheels after I had a blow-out. In this case, poor
pressure/spheres made the ride anything but hard.

What about the pump and the hydraulic lines? Does it have to be the
actual spheres?

I did replace the LHM a few weeks ago, with cheap no-name stuff!
AAAHHHH, it is so expensive... Why can't they have suspension like
every other normal car, this system is uber high mantainance.

The mudflaps don't hit the ground when pulling away. I will replace the
front spheres first, see what happens and then then do the back ones if
it is not better

Thanks for the advice
Duncan

A fiver per litre, and four litres every year or two?

Not really, no.

Between 5 and 8 £20 spheres to replace every three or four years.
£20 of genuine Total LHM every year or two.
About an hour or two labour to replace all those.

And what does that get you...?

No need to replace worn dampers - not that anybody ever does until they're
*utterly* f.cked.

No need to replace damp hygroscopic brake fluid (which doubles as a very
effective paint stripper) - not that anybody ever does until it's ruined
the brake wheel cylinders.

No dragging the arse of the car on the ground when you put a couple of
people in the back seat and some stuff in the boot.

Of course, if you don't do the basic maintenance in the first place, the
system's going to give problems. It was ever thus.

I agree. I've had 3 Citroens and the suspension was no real hassle. GSF
version of LHM seems to work fine and isn't too dear. Of course as you say,
if you leave it unmaintained then it will give hassle and at that point it
may be dearer than normal suspension especially if the regulator or pump
decide to leak.
