Ok, an update. I tied the brake lever to the grip and left it over night; master cylinder open with baggie keeping dust and dirt out. Bleed tubes were closed.
This morning, I noticed just a minimal difference in the pressure but still not enough to bleed the system. I disconnected the MC, held my finger over the hole and pumped. Brake fluid squirted out so I know that is working. (it's brand new, it should.) Put one end of a plastic tube on the left bleed nipple and the other end in my mouth. Opened the valve about 14 turn and sucked. Got about 1/4 -1/2 teaspoon of brake fluid. Closed. Stumped again. NOTE: when I removed the caliper originally after it froze, I put the end of the brake hose in a baggy so it would not drip all over the lot. (live in a condo, parking lot is my garage) Next morning, there was only about 1/2 teaspoon fluid in the baggy. Should there have been more.
Question 1: if I open the bleed valve and squeeze the brake handle, shouldn't I get brake fluid pouring out of the valve? I don't. I'm starting to think Larry is correct and it's possibly a collapsed brake line/liner which is not noticeable from the outside. As stated, my bike is a 2004 and has lived outside all of its life. Covered in the rain and snow, but otherwise uncovered.
Question 2: Is it possible to force fluid up through the hose, pushing the air out the MC? If so, what's the best process?
