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.
