So I decided to try to bleed the brakes to replace the old brake fluid. Got some Valvoline Synthetic Brake Fluid and picked up a "one person brake bleeder kit". I started on the rear passenger caliper, you stick the container to the frame above the caliper (it has a magnet), hook up the hose from the caliper to the container, and then losen the bleeder by one or two turns, then go press the brake a few times. It worked like a champ and filled up the catch container. I stopped when I got to minimum on the master cylinder. I tightened the bleeder, removed the container, emptied it, then went to the drivers rear caliper, proceeded to follow the same procedure, however no brake fluid came out!?!? I ended up turning the bleeder screw so far that brake fluid started seeping out around the threads, but it still would not let fluid out of the bleeder like it should. The brake bleeder kit was not clogged. There is no corrosion and the bleeder scrw looks to be intact. I didn't do any of the others 'cause I will be doing the front brakes and birfields very soon and will do it then. The question is, what the heck is going on down there? Any ideas?
