I'd..didn't read entire of all post..just have to say I've changed mc, on cars, did plenty of brake work for myself bled and have never had a problem as much as front brake on my xs650. I changed the line bled the mc and line and caliper every which way hf didn't have the recommended pump in stock...I wound up bringing the whole bike to local shop and he got the front brake like as good as can be. I can't really say wtf was going on.
