I'd start off rebleeding all 5 brake bleeders. LR, RR, RF, LF, then LSPV.what do you mean by adjust up the shoes?
and will 89 4wd calipers bolt on?
*If your rig even has LSPV is would be the rod arm deal coming from the brake line junction on the frame before the soft line to the axle.ok but that doesnt answer all my ???????
