Ok, so I'm changing out all of my brakes, lines and also all of my fuel lines on a 98 pace car that sat in storage for about five years with two flat tires. I'm cutting out every line replacing all of the hoses rotors brakes etc. I guess you get the picture. So now I cut out the back lines going to and from the valves to get the fittings off. I'm ready to re-plum the rear brake lines but the valves don't have a arrow for flow. So now I look in the Pontiac service manual and all I can find on them are they control flow to the rear wheels and not to clean them because they are filled with special grease. Does anybody know how they go back?
