I purchased the ALL PRO OFFROAD extended brake line for the rear. Went to swap it out yesterday (saturday) and now I cant bleed the back brakes...? The LSPV does bleed but from there on there's no brake fluid pressure at the bleed valve at the rear wheels. I have added the OME901 springs last weekend and was able to bleed the brakes then but I can't remember if I had it set on the ground off the jack stands? I've been spinning wrenches for quite some time, but this now has me baffled. Does the LSPV have something to do with this?

If it is on jack stands and the axle is drooping the the lspv may be closed, lower rear or raise axle. If that don't work pull the brake line to insure its patent.

 

got everything hooked up right?

the LSPV gets two lines from the front of the truck: one from the front brake circuit and one from the rear circuit. The one from the front circuit can be 'bled' at the LSPV and the one from the rear circuit cannot- it requires the lines to be bled at the wheel cylinders.
There is no "cross-over" between the rear and front circuits. They are completely isolated from each other.
