Rustystud, are you saying that if you change from one fluid to the other, you should also change all your seals? I'm curious now what is going on with the seals? If you go from 5 to 3 is there a difference from 3 to 5? I can see that after a change from one Dot to the other there would always be the question if all of the old was out, which raises the question what happens if there is a small amount remaining? because unless some kind of solvent was used or you replaced all old seals with new seals the old seals would still be wet with the old fluid. Is that where you are coming from? I've read many posts where guys have converted to dot 3, but I haven't read where they replaced all seals. I haven't read where they had problems after the change.
The fluid in my MC was not separated. I sucked fluid from the bottom and the top of the MC reservoir and it looked the same. The fact that the MC access door was labeled Dot3 and there was a partial bottle of Dot 4 in the tool box means a change was made. How well that was done I don't know. Right now if I pump the pedal 3 times I have brakes if I pump again I have more pedal. If I let off the brake pedal I have no pedal until I pump again. Would this be an air in MC problem? or a MC failure. I see no exterior leaks. Thanks
