Im working on a past Duntov winner 63 Coupe. This car has had about 1000 miles put on it sense restored in about 1975. The owner decided to drive it and the brakes were locked up (Drum). I removed all 4 wheel cylenders and the power brake master cylender. All 4 were stuck and full of dried fluid. The master cyl. had been sleeved in the 70s and was still good condition . I rebuilt all 4 wheel cyl. and the master cyl. now here is the problem . We are trying to use silicon fluid .We tried bleeding and could not get any pedal or fluid out. We tried gravity bleed no fluid . We used a vacuum pump and got lots of fluid from the master cyl & all 4 wheel cyl. Still no pedal And now if you try to vac.bleed it nothing comes out. So I seem to get fluid at times when vacuum bleeding other times nothing . I am going to check the master cyl.vent holes and the size of the new seals and maybe give up on the silicone . What do you think?????????? Bill
