Today I started to connect up the master cylinders to each other and to the resevoir. I didn't finish it yet as I am still waiting for the fittins for the parking brake. When I ordered the parking brake I completely forgot to order the four 1/8" pipe to AN fittings. The nylon brake line wasn't to bad, but my past history with this type of fittings is they will leak at some point. Honestly I have grown to appreciate the push on type of o-ring fittings. You can get this type of fitting for air brake lines but I don't know if they are resistant to the brake fluid.
