Interesting. From what I read earlier, you are experiencing the opposite of what happens for most. That is, with less tension on the spring, the arm would be closer to the end screw, and from what I read earlier, should apply more rear brakes?

At least, that is how it seems to be on my car. Raising the car causes less tension on the spring, and raising it is what happens when less loaded, and less brakes are needed.
I've read thru this thread, and several others. I've seen mentioned that less tension = more brake, but it does not seem right. At least not to my car. It might be a different setup in other markets for what I know.
I have a friend at Nissan here i Norway. He told me to have a look at this one, to see the principles of the valve:

Hi all, my 06 3L GU wagon developed a problem when I tried to tow a heavy caravan. The rear brakes locked up. After going through the obvious check list it was decided that the proportioning valve was the problem. Couldn't find a new or used one in Australia and the new one from Nissan would have to be imported, so for shits and giggles I took it off and took it apart. The only thing that seems out of wack is a rubber seal - appears loose. Thanks for this thread, very informative.
Does anyone have a wagon wrecking atm and would sell me the unit?
Are you ready for Christmas?

Do you need one immediately?
Have you got a pic of the offending valve.

I have one here will just have to see if it will suit. At the least it should get you out of trouble. I can then point you in the right direction to get a genuine one in 5-7days.

If you raise the rear (back to unloaded height to remove the sag) when loaded with the air bags the proportioning valve then bleeds off brake pressure as the
Valve thinks the vehicle is unloaded.
Of course if you have ABS no problem as no load sensing valve, however one more thing to go wrong

Our 02 GU has ABS and a load valve is fitted to it also.

THEN IT'S A COMPROMISE

The user compiled manual with tips on how to do various jobs is great.
But in the manual I have, lifted from here, sm7e-2y61g1 sec br page 7,
has a different procedure, (having trouble inserting a picture for some weird reason).
not having a shot at any body for a split second, may be I missed something.
After having trouble re- setting the lsv due to lift, referred to my manual & found this procedure.
Don't doubt for a second angle needs to be closer to 90deg after a suspension mod but maybe just not as critical to 90deg as one may think going by this manual pic.
Also in this manual a LSV is fitted to both non abs & abs equipped models.
straight from y61 manual
Ensure vehicle is unladen condition.
Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions .
Have a driver sit in the driver’s seat and one person sit on the rear end. Then have the person on the rear end slowly get off the vehicle. This is necessary to stabilize suspension deflection.
Gradually depress brake pedal and attach a lever to the stopper bolt, then adjust length “L” as follows: Length “L”: Approx. 175.2 - 178.2 mm (6.90 - 7.02 in)
cheers

Hi Robo, sorry I didnt get back to this thread until today, looking for answers to another problem. Yes I followed the destructions you wrote and set the spring half way between the recommended distance. Seems to be working fine.
