How do you get the proportioning valve off the axle on a 76, thwe flex hose is cut and needs to be replaced, but it seems as though the hose is crimped inside, I can only assume that you have to take off the P. Valve off in order to replace this hose? Thanks in advance,
There's no proportioning valve on your axle housing. That's the brake hose and hard line junction block. Just remove the bolt on top of the brass block...should take a 9/16" socket. You'll get a new brake rubber hose with the new block. Be sure to disconnect your hard brake lines before removing the block bolt and plug the lines with a small rubber vacuum cap so you don't lose all your brake fluid. You will also need to bleed your brakes once you replace the rubber hose with brass block piece and hook up your hard lines. Also double check the vent hose that connects to the top of the brass block to make sure it isn't crimped anywhere.
Sometimes a torch comes in handy for removal of frozen /difficult fittings.
Also make sure the vent lines not blocked, You don't know if a creature built something in the breather because they were attracted by the smell. Hell, the smell of 90w-125 attracts human males.
I don't know about you guys but I ALWAYS move the brake line nut back and put Never-seize under the nut. Usually getting the nut loose is easy, but getting the line unseized from the nut can be the difficult part. That and whenever I put on new brake parts (calipers/wheel cyls. ) I remove the beeders and do the same. I hate fighting with little bolts that like to break off.
