Only if you are going to rebuild the brake system would I take it apart. I use a clean sucker bulb and remove all the old fluid from the master cylinder. I also wipe the inside that I can get to. Than put in new brake fluid and keep bleeding till it comes out clean. A few years back I converted a brake system to silcone on a collector car. Their I replaced everything but the metal lines & flushed the system out with denatured alcohol and air to dry them out.Than followed with new silicone fluid.Good luck on getting the bleeder screws to open.

do NOT use silicone(DOT5) brake fluid!! I made the mistake on using it in my mustang, and am about to drain it all out, tear my brakes apart, clean the seals and put DOT3/4 back in!
WilWood brakes has an interesting article on it that I'm going to try to put up

Wilwood does not recommend using DOT 5 fluid in any racing applications. DOT 5 fluid is not hygroscopic, so as moisture enters the system, it is not absorbed by the fluid, and results in beads of moisture moving through the brake line, collecting in the calipers. It is not uncommon to have caliper temperatures exceed 200° F, and at 212° F, this collected moisture will boil causing vapor lock and system failure. Additionally, DOT 5 fluid is highly compressible due to aeration and foaming under normal braking conditions, providing a spongy brake feel. DOT 5 fluid is best suited for show car applications where its anti-corrosion and paint friendly characteristics are important.
