In all likelihood, those are nylaflow lines.  If they are 1/4", you'll be doing 
yourself a favor by changing them out for 3/16", or even 1/8" lines.  I've run 
across crapped up brakes where the Mil-5606-H had separated and turned to muck 
a few times.  I remove the pucks from the slave cylinders and clean and dry 
them thoroughly.  Remove the O rings from the pucks and clean the grooves in 
the pucks and clean the O-rings as well if you intend to re-use them.  I prefer 
to replace the O-rings.  Also inspect the walls of the slave cylinders for 
pitting.  If pitted, you can work them over with some emory or crocus cloth.  
Just make sure the scratches are radial around the bores.  Pump the master 
cylinders until nothing comes out.  You can add some more 5606 to the master 
cylinder reservoirs and pump it through if you think you need to.  Reassemble 
and fill the brakes again from the bottom up.

Subject: KR> Tips for Flushing Brake Lines?
I'm working on something that's been sitting too long. The red hydraulic
fluid in the lines and in the calipers has gelled. I haven't gotten into the
brake cylinders yet but that's coming.

Does anyone have suggestions for flushing the goo out of the flexible
plastic lines? Sorry I don't know what type of clear plastic they are made
