Spheres

Post by **user_3150** » 08 Aug 2004, 11:37

Morning everyone, I have just replaced the rear sphere's on my Xantia so now I've done all six. I can't believe what a diffrence it has made and not really that much of a job. Just a quick question to ask the rear still sinks slightly when engine is off. Is this because it's an estate (2000 model). There are no leak's and the ride, brakes steering are perfect.

Morning Alec, sad this one at this hour[|)] should still be in bed!!
How much does it sink? My estate settles a bit, just a few millimeters but that is usually after the dog has got out and he weighs in at 50kgs. It usually drops a little once the brakes have been released after stopping and then picks up. All of this really indicates that the rear height corrector and accumulator sphere is doing it's bit.

It's normal for rear end to sink a bit (mine 1-1.5 cm within about an hour), because this in fact activates anti-sink valves.

Mine also sinks about an inch when left, its also the reason I always crack my head on the corner of the tailgate when putting the shopping in.

That sounds about the same as mine (about 2cm ) cheers for the replies. I have also noticed since that the brakes are a bit spongey any ideas anyone?

Before i had the rear height corrector done,mine always sat lower on the back,and sank down to the mudflaps.After it was done,it sat perfect & sat level when i turned the engine off.But sinks about an inch over night,as above.

When I bled brakes after changing fluid to hydraclean there was a lot of air at each corner, I had recently changed all the spheres (All duff) I think I read somewhere that nitrogen can leak into fluid from the spheres, They were defintely better after but got a lot better after replacing cleaner for Straight LHM, this may be a combination of a good cleanout and another bleed. I gave the brakes a checkover as well (clean coppergrease etc) and this gave a nice response.
Has the accum sphere been changed recently I have read this can give changeable brakes if its on the way out. Other members may be able to help.[:)]

Did you bleed the brakes? I didn't, When I eventualy did after doing the fluid (twice, don't ask) The change was remarkable should have done as Anders and other said[:I]

No I haven't bled the brakes but I need to change the front disk's so I will bleed them at the same time. Cheers for all the help.
