I have a Discus-2b with the factory Tost 5" wheel also. We had real
problems bleeding all of the air out of the line. Biggo at the factory
even sent me a pdf file with pictures in order to do it correctly from
the bottom. It was a real bear to get all of the air out. Also,
adjusting the cable/brake handle so that there is no play helps a lot.
Finally, get a new brake pad even if the old one looks OK. The new
one will be thicker, so the caliper won't have to squeeze over as
great a distance to apply pressure. All of these items add up.

michael, can you post the pdf? I'm convinced I've done everything possible regarding bleeding, but still don't have good braking. So I don't expect it will help, but I'm desperate now. thanks.
