I've got a Trek 6300 with Juicy 3 disk brakes. Stupidly I opened them up and a little (2-3 drops) ran out. Now when I pump the brake it closes the wheel enough to stop the tire from spinning with no one on the bike, but not enough to stop the bike with me on it. Do I need to do a full bleed (as shown on many youtube videos) or is there another way? Thanks in advance for any help.
