For my next trick i shall attempt to clean out the hydraulic system of my BX.
I intend to run some hydraflush through the system and plan on emptying the main resovoir, filling it with hydraflush, then bleed it through the pipes through the brake calipers. Is this the right way of doing it?
What problems am i likely to encounter and how long should i keep the hydraflush in there?

Do you guys want to hear something amazing????
I tried to find hydraincage in my country and even the main citroen garage in the country did not hear of such thing....they all tell me they have no idea what i am talking about...
And then they wonder why Citroen cars have bad reputation and so cheap comparing to other manufacturers.

The following site provides excellent instructions on all manner of Citroënistics - the following tab deals with just LHM change:

This is what Philippe at Medway Cit told me, and what I am about to do this afternoon:
1) Undo pressure regulator (PR) release valve 1 turn ONLY! Mark for reference (12 mm bolt on front side of PR)
2) Disconnect fuel pump hoses, taking care not to lose double washers inside inlets.
3) Label and disconnect LHM pipes. The thick one furthest away from you as you look at the engine from in front of the radiator is the out pipe, the other thick one nearest to you is the return pipe.
4) Dismount LHM reservoir, empty contents, clean filters and inserts taking care with sharp edges
5) Remount tank and fill with Hydraflush
6) reconnect 4 slimmer hoses to tank
7) Remount and prime diesel pump using large black rubber pump button on front.
8) Attach extension pipe to return pipe and route it to a vessel to catch LHM
9) Attach large funnel to out pipe and fill with Hydraflush, keeping it well above tank level. This is to prime the pump and to ensure no air gets into Hydraflush
10) Start engine and when Hydraflush is gulping in the funnel, remove funnel and reattach pipe quickly to reservoir, taking care not to allow any air into mix.
11) When clean Hydraflush is coming out of return pipe, reconnect to reservoir.
12) Retighten PR release valve bolt
13) Put suspension on highest setting and put car on axle stands
14) remove road wheels and bleed brake caliper until clean Hydraflush is apparent
15) Replace road wheels and go up and down x50 from highest to lowest. This will kick the Hydraflush around the system.
16) Run for 1000-1500 miles and replace with fresh LHM, following above procedure.
Let me know how you get on!
