Bleeder screws... If they break off it's reason for a new caliper
(IMO). I find the correct sized wrench for the bleeder and tap on it
with a small hammer. Tap tap tap will generally get the bleeder to
move. Lightly tap tap tap, I want it to move not break it off. In a
rust prone area (Minnesota) I have done the tap tap tap thing for as
long as 3-4 minutes before I broke out the heat to try & get the
bleeder to move.
