Hey Guys and Girls  

My Trackickvit is lifted with the pro comp 3" system. Now because I don't have a spacer on top of the axle (yet) my LSPV (Load Sensing Proportioning Valve) is way off of the normal position so my rear won't brake. Is there a way to adjust that? Because it failed the yearly check up on this (mainly) and I can't drive it now  
I have the older type with the spring and arm assembly.

If I remember correctly it is actuated by a long spring that is hooked to the upper V-bar. Why could you not get a longer attachment and or just disconnect it till after the  inspection. That would make the rears have max pressure going to them during the test (If i am thinking correctly)

Hey Zig,

Thanks, I think I might fab up a little spacer on it so it'll be in allmost the original position or something, must try driving it with it disconnected maybe see if it works  

p.m. Safarikick. He made a spacer to raise the arm up to the original position off of the third member. His problem was a loss of rear brakes due to the angle of the arm. When you raise the frame it changes the angle at the third member,causing the valae to DECREASE rear brake pressure. Hpoe this helps!

to get the rear brakes working good, with out a spacer, you need to pull the lever on the LSPV down, or get a tighter and shorter spring. seeing as the lever is on the other side of the arm mounts, the lift makes it think its light, and not loaded.

so try a shorter spring 1st, or a tighter one, and if it doesn't work, you may need to make up a spacer for the ball joint.

i dont think it's worth running with it disconnected, even though the rears are drums after all.

hope this helps,
Steve

A ball-joint spacer is in the works   and so is a driveshaft spacer. So I'll get my downtravel back   but for now I think I'll try to adjust the lever so it sits lower, maybe tightening the screws on top?
Thanks for the input.

im haveing kinda the same problem except it acts like its not releasing the brakes once i hit the brakes it feels like the emergency brake is on like the valve isnt  letting the pressure off the rear brakes,thinking about taking the valve out?

I have my proportioning valve tied wide open.I hooked the spring to the bracket that holds the upper v bar.  Ive had it that way since day 1. My brakes work perfect. Might want to try it.

Could the LSPV be bypassed completly and a adjustab;e proportioning valve used??

I guess this is why my rear brakes SUCK huh?

I dont' have one of those on my 95 and the rear brakes suck, too.

So that is opening it all the way up, and in a sense, bypassing it, correct?

Think you could snap a pick for me? PLEASE?!?!?!  

The LSPV is an advustable proportioning
valve, better than any you could buy to
replace it, remember the rear balljoint spacer
that I was trying to get a group buy on ?
Well it addresses this problem, and is one
reason I built it, also no LSPV will lock up
the rear brakes, something that you don't
want happening on a SWB vehicle

For all you guys with crappy brakes, get
some 4 door brakes, or switch to rear disks,
other than that, you could advust the LSPV
to increase the pressure to the rear brakes,
making them work harder, yet still adjusting
the brake force with the weight and axle position

I think tightening the nut on the adjuster will
increase the brake force, go slowly, too much is
a bad thing, you don't want lockups on that rear axle

I don't have a  LSPV on my 95 2dr.
I guess I should look and see if it is missing or didn't come with one. :-/

Some come with rear antilock instead.

Some come with rear antilock instead.

Thats gone with the ARB set up. I wonder if thats connected somehow to weak rear brakes?
