hi chaps heres one you will probably be able to solve. my xantia 2.0l t estate wont lift up at the back and the brakes dont work unless you press hard then they work too well ! working it feels only on the front the car has hydractive suspension. the car hasnt lifted up properly since i got it really slow to lift sinks when engine off and didnt lift right up the reason why it wont work at all now is because iv had the front jacked up today working on another problem cheers chaps

Stuck rear height corrector.
As the rear brakes are tied in to the load on the rear suspension then they won't work.

Much good advice on remedies here.

You shouldn't need to but it never hurts.

If it still isn't rising I suspect that the linkages are incorrectly assembled or have been distorted while the mechanism was seized. Happened to mine and bent the linkage on the ARB enough to warrant replacing it. Inexpensive, fortunately.

From your original description, I think you have a system pressure problem, and maybe the rear isn't rising due to the anti-sink valve remaining closed.
The front brakes do most of the work, so I can't see any problem with the rear suspension causing a noticeable lack of brakes.

Does the "stop" light go out normally after starting the engine?

just put on a good hc off other car no difference mate the front brakes are fantastic but no back brakes stop lights are normal

How can you tell that the back brakes are not working?

No back brakes can also be due to the corrosion build up between the calipers and the arms, pushing the calipers off track enough that they prevent the pads working on the discs.

finally managed to bleed brakes back brakes now working but now the rear suspension is stuck at full height the height corrector fitted is a known working one and the linkage appears to have been put together properly just want to make sure about the height corrector pipes there are 2 side by side i take it that the rear pipe goes into the rear hole and the front pipe goes into the front hole and they are not supposed to be crossed

No, they should not be crossed. Itr should be fairly obvious by their "lay" which goes to which port. If need be, I'm sure one of our members can take a look under theirs and confirm. I can't as all mine are hydractive and different in their pipe layouts.

If the HC to ARB clamp extension (the bit where the white link attaches) has been badly bent, that can also account for it. The rannge of movement is so small on the HC that a bit of distortion can make all the difference. I had this with my Sliver Activa. It was always on the ground it it was all because the whole HC mechanism was so far out of adjustment. This can happen if something gest bent for whatever reason.

iv managed to move the hrc arm to a drivable height but adjusing the the height switch or sitting on boot doesnt alter it i will take it to a specialist for repair cheers for advice

got it sorted now i had got the two pipes that are side by side the wrong way round i asked this question earlier yes they do cross over one is the feed for the brakes and the other is the feed for the suspension . the single one on the L.h.s is the main feed worth remembering eh
