70 Hydraflush

Suspension
70 Hydraflush
I've just had a revelation and thought I'd share it with those of you who have similar problems.
My 1990 G 2.0 carb model had been getting very lazy at pumping up and was equally quick dropping
(about 5 mins), I replaced the LHM with Hydraflush and within an hour's running it's changed to a car
that pumps up in less than 10 secs from overnight standing and stays up for hours (oh , fond memories
, but that's another story !). Also the steering is much improved and the ride's better too !! So take my
advice , if you've got over 100k on the clock , flush the system & get a new car !
====
This is remarkable. After 100K the car sinks sooner and rises slower because of a worn brakeservo or
command (don't know the word in English). This was shown last week at a technical event by Citroën in
the Netherlands. I don't see how hydroflush can help if one has a worn brake thingy?
====
I agree, this is most interesting, what other effects did this stuff have Mark, did it help free up the front
suspension (some say it helps get rid of the creaks and groans on strut suspension).
Apparently Arthur, the rear brake pressure on the BX leaks off thru the "Brake Valve", which causes the
back end to droop quickly after stopping. This flushing stuff, which is pretty expensive, must free up the
seals.
Mark, I am sure the BX list would be interested in this as well.

Arthur .. yes it surprised me too ! Another 200 miles and it's still getting better !
Chris .. yes it has helped the creaks and groans and the pump's quieter too !
As to the cost , £15 supplied & 'fitted' by my local specialist ( in Plymouth UK), I leave it in for 1000miles
and then change back to LHM. I reckon that to be very well worth it!!
====
Were all the filters and the tank cleaned out when the fluid was changed?
To use the cleaner, just change the fluid (cleaning filters and tank), then put in the flush instead of new
fluid. You will need to bleed it through the brakes.
After about 1000miles of normal use, repeat the change & clean. Again, bleed it through the brakes -
everything else is bled from the main bleed screw
In and Out
Just how thorough do you have to be when changing LHM.
Presumably you just change what is left in the reservior when you are at minimum height. So there is
always old LHM left in the pipes.
Same question goes when you use this hydraflush stuff. Would the people who have actually used it
come forward and actually tell us the procedure they have used to get it into and out of the LHM system!

I used hydraflush in my XM recently.
