Hi! Finally logged in after being away for a while.
Welcome back to the forum, you have been away for a while, 5 years! Nice to see your two cars side by side, the limo style of the CX next to the more angular BX. Sounds like you have a bit to do regarding the BX but at least you seem to know what needs attention. Keep checking in with any progress and pics when you get started as you suggest. :D
Prefer it to the Lamborghini, like Signor Gandini!

Well the car came back from the garage yesterday. Repiped front to rear, 4 new tyres, an MOT. It's taxed and insured. It had new front ebc pads and discs, new pattern hand brake cables before it went in. It's on hydraflush too.

It actually stops reasonably sharp now. There is a slight delay, somewhere between the pedal spring and I guess the ABS pipes. Still need to do an emergency stop and see if it actually locks up or if the ABS will kick in.

Nearly 300 miles last year! Plan is to do considerably more miles this year. As soon as we are allowed out.

That's good to here Vanny, so you are all set. Hopefully the weather will continue, April has been good so far, it is typically the month I can allocate time to the BX and I was looking forward to that in particular this year.
You have that "Hydraurinçage" in then, need to cover a few miles for that to do it's thing, + - 1000 or so?
Be careful with that emergency stop, you don't want to split that little rubber domed part on the valve.
I think you will have reasonably fresh one in there but I think they can be split regardless by an overly enthusiastic foot having spoken to a "old skool" Citroën mechanic. Understanding what is happening at the pedal as you do is a good start.

At least it is pretty busy on here even if it is just yourself, Niko9 and me. 😉

Very much depends who you speak to! Pleides, who i bought it from a loooong time ago, used to run a car (possibly a yellow GSA) ONLY on the hydraflush they sell/sold. Its not the Total/Citroen hydraflush mind, its something used in aero industry, coloured green :D

The difference is already notable, driving back from the garage it feels much more like a Citroen BX 16v should. Not so soft that the bumps aren't noticed but far far better than say a Bentley Continental GT which is the only thing I have for a back to back comparison on those roads. I figured I might need the spheres changing as they are very old, but actually now its had a clean, they don't seem too bad. The old accumulator was marked 2006 on the box (from a photo) so that's been changed for a 'BOLK' one.

Have to say, whe. I hydra flushed the Xantia with this stuff, the difference was remarkable! From As soon as I refilled and bled it through with hydraucinacage, it rose smoother, rode smoother, broke better etc. Even ran better when I poured the old lhm into the tank..... 😬

My understanding is that yhe structure of LHM is long chains. With age the chains get broken up, making the fluid thinner. Hence new LHM always performs better than broken up old LHM.

But if I read that right Timmo, once you cleaned the system out with hydraflush, you put the old LHM back in and out was still notably improved in performance? Was the old LHM actually old?

My only concern with hydraflush is when I used it on the 19RD, it blew one of the rear curly brake pipes in spectacular fashion! I do wonder if the clearing of crap out of the system actually increases pressure in some pipe sections which is what did for the 20 year old pipes🤷‍♂️

Not back on the lhm tank vanny! The Other tank! 🤪 🤪
There is always an element of cleaning off the buildup in the pipes weakening them for the inevitable pop, sure was the Xantia that popped one on the mot test one year!
