Well I used DOT4 which is what the cap on the master cylinder said to use.Maybe the brake fluid you used was incompatible with what was already in the system?
Maybe it is time for new seals?
I am in agreeance on the idea of new seals, but it's odd that both clutch and front brake master cylinder lost pressure after the process...
I did just read that one person had been having a similar issue, and he added Teflon tape to his bleeders and it took care of the issue. He said air was escaping through the treads of the bleeders. I may try that remedy to see if it does the trick.
But likely I am going to rebuild both master cylinders.
