Re: Solidified Brake fluid in master cylinder

You should disassemble the master for a complete cleaning and replace all gaskets and seals. Assuming you have TreadleVac, minor overhaul kits are widely available. Not sure about standard brakes.

If the tubing is not rusted, you might be able to chase through with a piece of wire, flush with alcohol, and repeat as required until your confident the path is clear.

Don't be surprised if the pistons are stuck in the wheel cylinders - due to crud and corrosion. If so, considering time involved, it's probably cheaper to replace than over haul. New cylinders should be available through any parts store worth their salt; Stay away from mass market stores that only carry the fastest moving stuff. Even if there's no catalog listing for Packard, a good counterman can study the casting numbers and match them up.

If the wheel cylinders are not seized and the bores are not pitted, then disassemble and replace the seals. Wheel cylinder kits might not be necessary, however. It used to be that good old parts stores carried an assortment of these "cups" for wheel cylinders - not sure what inventories are these days.
