Can a faulty sphere affect brakes?

[martscar]

Hi all.My quest to get the brakes back to how they were on my HDi has made me look at when they changed and it seems that they altered after I changed the accumulator sphere. Can this be so, I thought it just gave back up pressure in case of a line failure. I just can't leave it alone ,fantastic motor otherwise . Also does anybody know if there is a hook or clip I may have lost that fits on the fluid tank top at the back and locates in the loop of the retainer bar.Martin

i wouldnt worry overdully regarding the tank lid, as it will not affect the hydraulic system much at all,
can you post picy's of the bit you are having trouble with,


a duff sphere can affect the brakes, especially if it dumps its gas into the system

On the XM LHM plastic reservoir one end of the metal clip simply fits into a moulded hole in the tank side.

Kenhall is correct there;s just a moulded section where the end of the wire locates.. a bit strange ..but it does work eventually

[martscar]

OK thanks for the info, looks as though I have lost something cos the back is the same as the front of it which is just an inverted U so I cant hook in .May be best just to re-shape the hold down rod..I have looked at the spheres and all seems well,and no rapid ticking-- the braking is instant -not delayed ,just not as assisted as it was.Next thing is a new H P pump I suppose. At least I know now that an iffy sphere will have a braking effect. Good stuff

can you post some picy's of you tank and holding down rod,

hydraulic citroen brakes are not assisted ( like conventional brakes ) , they are powered, the braking pressure is there all the time, and the pedal just allows the hydraulic pressure through in more or less two stages, light braking/pedal pressure = normal braking or full on/heavier pedal pressure = locking everything up,


this is usually air in the system cause's you to loose the first light braking action, so all you are getting is the second stage of you pedal/dosoure action,

basicaly the pedal/dosour valve has two braking pressures, normal braking and locking every thing up,

as it seems by what you are saying you only have the second action ( locking up/all or nout ) 99% of the tome this is down to air in the brake circuit,

i would say just give the brakes a thorough bleeding through

[c.morewood]

Hopefully this will help

Hello all, at my xantia sometimes I have same problem like martscar at light breaking. I bleed all 4 calipers but no air come out. When I push hard the break pedal make a sound...pufff.

Going by that picture you are almost there. The clip needs to be in that inverted U moulding.

[martscar]

Thanks to Malcolm for your continued info, the brakes are there but will not lock up. Reckon you are right, but I will give it another bleed. Got to acknowledge Chris for his picky , I don't know how you got it but it speaks a thousand words. I was a bit anxious it would not stay in that position and a bit was missing but I am obviously mistaken..........again. Saved me a lot of fiddling.

[martscar]

Hello xflref,thanks for your input. Keep me informed will you please.Thanks.Martin

that picy is not of martscar but kindly posted by Chris to show Martin what should be there

I hadn't noticed James..thanks for pointing that out.. took the photo in a hurry .. as my LHM tank was off.. thought it might be of use.
You're quite correct the small bend in the wire, just before the loop should locate into the "U" on the tank.

Just a quick apology to James, I am getting people mixed up and he has been so helpful .I may have credited the wrong people .To all concerned ,thanks very much for your help, it is really appreciated.Martin

Martin you dont need to apolagys as you did not confuse out
