Hi,
My "newly-returned-to-the-road" Xantia HDi has a peculiar quirk with the brakes. When releasing my foot from the pedal there seems to be a momentary lag before the brakes release. Is this typical of Xantias or is my braking system on the blink?

Re: Xantia brake "lag"
Tim, its always worth giving the brakes a good bleed. Air in them can affect them in strange ways and unlike air in a conventional system.
Normally though air causes a delay rather than holding them on but given how strange things can happen, bleeding must be the first task to do in looking at this issue.
Other causes can be binding callipers, maladjusted or seized parking brake cables or a problem in the dosuer valve not allowing brake pressure to release. That is very rare though and unlikely. Deteriorated flexi-hoses could also be the cause.
I'd start by bleeding and whilst bleeding check all the above as well, paying particular attention to the parking brake cables and binding callipers.

Re: Xantia brake "lag"
The one handbrake was binding but a quick lubrication workout session seems to have it cured. I'll have to look up bleeding Xantia brakes as I hear there is a knack to it.

No knack Tim, it's actually a lot easier than a conventional car. Nipples rarely seize and it truly can be done by one person with nothing more fancy than a broom handle...
It's all in this sticky thread...

Re: Xantia brake "lag"
Sounds pretty straight forward!
on another note... daft question time, how to I check the level of the LHM fluid?

Set the suspension to high, allow to settle for a minute or so and check the little orange 'Coolie Hat' in the LHM reservoir sight glass is between the two red rings.lankytim wrote: on another note... daft question time, how to I check the level of the LHM fluid?
The level can only be checked on high and on level ground. On normal height setting the level will always look far too high...

Re: Xantia brake "lag"
It might be obvious to us old hands, but its worth pointing out the engine needs to be running for this. Also I would suggest leaving it on high with the engine running for 3-4 minutes, 1 minute isn't nearly enough for mine to give the correct reading, probably because the rear height corrector linkage is a bit restricted in its movement thus takes a lot longer to fully pressurise than it should.CitroJim wrote:Set the suspension to high, allow to settle for a minute or so and check the little orange 'Coolie Hat' in the LHM reservoir sight glass is between the two red rings.lankytim wrote: on another note... daft question time, how to I check the level of the LHM fluid?
