Hey guys,
Need to bleed the master cylinder on my 1975 Chevy 3/4 ton van. My local auto parts store carries generic aluminum "hard" lines with the various flare fittings on them but I don't know which sizes thread into the output ports on the master cylinder. The employees there are totally clueless and they won't loan me a master cylinder so I can see which ones fit myself.
All I need to know are the flare sizes... the van uses power assist front disk/rear drum configuration with a dual master cylinder and the front brake fitting is a different size than the rear brake fitting.
