[Shop-talk] Converting a bubble flare to a bleeder port?

[Steven Trovato]

Hi Jim.  I don't have a definitive answer, but since you haven't 
gotten any responses I'll take a shot.  Calipers and cylinders I have 
seen seem to have ports that are the same for the line and the 
bleeder.  Sometimes they are even shipped with the bleeder in the 
wrong  port.  I would think that a bleeder that is made to work with 
the European system would work on that splitter.  I would say, just 
try it and see.  If it seals and doesn't leak, great.  You can always 
go back to other less elegant options.  If nothing else, maybe my 
comments here will encourage someone more knowledgeable to respond.
