Another Brake Caliper Question

[Acekraut11@aol.com]

Hi List,

After many hours of cleanup work, the calipers are looking pretty good.  The 
one area I would really like to clean is the paths that the brake fluid takes.  
Does anyone have a tool that they use to chase these paths(I am sure there is a 
better technical word for it, but I must still be half asleep since I cant come 
up with it).  Thanks in advance for your help.
