I have recently put Hydroflush in my Xantia and am due to replace it with new LHM.
I was under the impression that I only needed to empty the tank( after lowering the suspension), and empty the pipe connecting the tank to the pump. After reading some of the posts in this forum I think I may have to bleed the system from the brakes ETC.
I would be pleased if someone would put me straight on this as I am a little confused.
Whatever I need to do it will be worth it as the car is running smother even with the Hydroflush than it was b4.
Thanks
Andy

Hi Andy - Yes - you should bleed the system on each wheel because the pipework to each wheel are dead ends. If you don't bleed, you are left with old fluid in the pipes irrespective of the new LHM in your tank. You should really have done some bleeding when you put in the hydraflush. You could do it now and bleed until you see hydraflush running out. A word of warning - you may find the bleed nipples reluctant to move and brute force could snap them. If so, try some gentle heat and a tap with a soft mallet. All the best!
Thnks John,
I have just started to bleed the brakes untill Hydroflush runs out, but it appears that it is all mixed in with the old LHM left in the brake pipes.
I now have the full gallon of Hydroflush in the system.
If I replace with new LHM when have done 1000 miles would that be enough. Or would you recomend that I start again with another Gallon of Hydroflush.
Also when replacing the new LHM do I empty the complete system of Hydroflush before putting the fresh LHM in?
Thanks
Andy

I think I might go with "cleaning" procedure very soon. My Xantia has 127k on clock. LHM was changed at 90k km (spring 2002). Present LHM has dark green colour ( 3 - 4 dcl in coca cola bottle). If I choose to bleed the brakes, how many litres of Hydroflush do I need? Would it be also 4,75 lit.
