If you are "losing" fluid from ONLY the 'rear' resivoir it would indicate a leak some where in the "front" half of the braking system. (You indicated you already replaced the master cylinder and wheel cylinders). It is a "closed" system and should not 'lose' any fluid ("boil-off" would seem unlikely for "normal" driving conditions). I would suggest a CLOSE inspection of the rubber lines at the front wheels...25+ year old rubber lines aren't very reliable and with the pressures generated in a braking system they are often the weakest point. Hope it helps!
: After finding my brake fluid at about 1/4 full after filling it up a week earlier, I decided it was time for some brake work. My '72 302 has 4-wheel drum. I replaced master cylinder and all the wheel cylinders and put new front shoes on and bled them. Its been four days and today the fluid was half empty in the rear compartment. The lines weren't in great condition but they didn't appear to be leaking. Is there anything else I can check when I am able to tear everything back down this weekend?
: Thanks
