A Porsche 911 Brake Job Gone Wild! Calipers, a blocked brake hose, and now a new Master Cylinder

Hi folks -- what began as a replacement of two front calipers has snowballed!  What a deal on the calipers, though. $30 a piece, no core, rebuilt and loaded from Rockauto. Along with Cliff Brockman, I found out yesterday that the reason my car was pulling at high speed was due to a blocked hydraulic hose line. Getting the old line off is always a challenge -- fittings rusted in place, delicate flange nuts, etc.  Cliff used a little trick in which he put a vice grip on the flange wrench to keep it tight while he tried to turn it.  Use of plenty of PB Blaster as well.  That hose was replaced yesterday, but we could not bleed the brakes properly.  The pedal still kept going down no matter how hard we tried!  So it looks like now because we bottomed out the master cylinder, that I need to replace it as well.  A job for next weekend, unfortunately.
