bx sinking rear end
Hi to all those out there that think flushing hydraulic system is fix all be it temp. The true fix for this prob is to replace brake doseur valve with new or factory re/con because rear susp returns through dozer valve, when the seals get worn they cant hold rear susp presure, so it seeps back up through system it dose not appear to make any difference to the normal running of the car, so most people dont have it fixed. regards to all Malcolm
I believe sinking rear is one of the mysteries that will never be solved satisfactorily.
What jeremy said is true (many made the same experience). I think the speed of sinking also depends on temperature, LHM type/condition, car load or God knows what other factors.
There are days when my rear sinks in 30 mins, other when it stands up for a day.
Funny thing is that when I put in Hydraurincage (thinner), the rear sinking was slower than when I replaced the stuff with standard green LHM (thicker) again. I thought it would be the other way around.
However, general opinion seems to be that if the sinking is not happening real fast (say, minutes), it is nothing to worry about.

when bx hydraulics are in good order they stay up for days it might depend on where your replacment unit comes from and what company re/coed it to how well it was done the rear susp fluid dose return through this also i have herd some people wrongly calling other units by wrong names such as refering to the safty valve on lower rear n/s of frot subframe as doser valve regards malcolm

Hello this is just to say that sometimes it does seem that the sinking depends on the time of the month,the phase of the moon or indeed any thing really. But I have been caught out by a new doseur that leaked worse than the old one (not a trickle but a continous flow in the return.) and a very simple one that was "Air" or I suspect gas from a sphere in the hydraulics which upset things.
Please check the return if doubtful.
Cheers
Geoff.

My STOP lamp and low brake pressure problems really started when I took out the Hydrorincage and put new "thick "LHM back in, having replaced HP pump FDV and lately PR which seems to have finally cured it, this car stays up for 24 hours just about, the flashing lamp also seemed to be related to temperature and therefore viscosity of LHM, it was better when the car and the weather was warm, moon phase is also likeley to affect the system[:D]
The rear of the car settling is not a fault, its a characteristic.
Jumping is likely to be dry struts, I have performed the Tom cure on two BXs now and it is instantly effective producing a much more supple front end, the drivers side was however still going down in a series of jerks until I tried a tip fron one of our antipodean friends, soak a strip of towelling in gear oil and tie this around the ram under the gaiter, the car now rises and falls smoothly.
