Brakes leaking within 200 miles-dot5 fluid

I recently put abody discs on my 1967 coronet. Manual brakes. New rear brakes and wheel cylinders. Flushed the system and filled with dot5 silicone fluid. Doesn't draw moisture supposed to be better. I did this in feb. Has about 200 miles on them. Last week rear brakes started leaking. Parked on lift. Fixed yesterday. Bleeding brakes. And the front calipers blow. Now they are shot. Is it the fluid? Or did I get 2-faulty wheel cylinders and 2-faulty brake calipers?
Do I switch back to dot3?
Replace the hoses now! Any ideas????
