Ok, I switched to stainless Steel lines and I cant get the pressure built back up. I got fluid flowing through, I dont see any more air bubbles coming out when I open up the bleeder thingies, and fluid IS coming out, so theres fluid in the lines, but I cant for the life of me get any pressure from the brake lever. Every time I pull on it it just comes to the handlebar without any resistance. This is the first time Ive ever done my brakes, so Im sure theres something stupid Im missing.
Thanks guys
Oh yah, this is on my 636 if that makes any difference
My guess is you have a large bubble somewhere in one of the lines.
This is where a mity vac helps because you have to push large amounts of fluid through.
I don't have one, and simply kept doing it by hand. I also took off the calipers and hung them up for awhile... basically trying anything to get the air to move.
Many people had success with tying the lever closed and let the bubble work to the top.
Did you add a bleeder at the top, near the master cylinder? That sometimes helps get air out.
New lines are hard... more air sticks to the sides...
have to tap the lines starting at the bottom and move up.
this will dislodge the air and it'll slowly work its way up
to the reservior.
keep bleeding sooner or later youll get a firm bite !

I had the same problem when I put stainless lines on my SV. I went to Sears and bought a mityvac to get the lines filled with new fluid, then I finished with a standard bleed. I'd highly recommend doing it that way...
Try removing the calipers, compressing the pistons fully in, reatttach he calipers to the bike, with the pads in, thentry again. Basically this allows for less vloume of space in the caliper, less air, and at the same time you may push some air up all depending how much fluid isin the calipers. Dont bother with the zip tie until you have some firmness, and the tapping of the calipers and lines while the zip tie is on is great for getting out that last bubble. Oh and bleed the master first, if there is no bleeder just crack the banjo as you would open a bleeder screw. If you have a lot of airin the master you have to get that out first!
Shoulda posted, I finally figured it out last night. There were no bubbles coming out of the left caliper, but I kept working it for a bit and a HUGE air bubble mustve been in there. Randomly once when I cracked the bleeder it like burst out. After I got that and a few leftover bubbles it was fine. It was pretty amazing, went from NO pressure at the lever to perfect pressure basically in one bleed after Id been doing it for about an hour.
