lifting '86 K20 - rear axle load/braking sensor?

New to this forum... just registered today.

I'm putting a 6" Skyjacker Softride on my '86 K20 suburban this weekend. I noticed what appears to be some kind of braking valve on the frame (lines go thru it to rear drums) with a knee/lever type link to a bracket on the axle. I'm guessing with a load, the lever on the valve is moved 'up' and this puts more braking power/proportion to the rear wheels? So, if I lift it, this moves the lever on the valve WAY 'down'. Would this decrease my braking power/proportion to the rear? Lifting the truck would at least prevent the lever moving 'up' all the way...... Anyone else considered this?

Also, any tips on installing this would be appreciated.... Like, Do I need the sway bar drop kit? Or, I want the softest possible ride from my lift - anything I can do to ensure this?

Thanks

C'mon guys... No replys? Is it because this a no brainer thing I should already know about or do I have a 'rare' load sensing brake valve option?

It looks like from another post Stomper is also installing a 6" lift on an 86 K20, I wonder how he's handling the load sensor. Probably get more response at www.coloradok5.com , they are more for 73-91 solid axle Blazers, trucks and Burbs. Though they do have a nice 69-72 K5 forum.
