Could be a mix of fluids that's giving you a problem too.
I have flushed it three times, but always used the same stuff I use in my cruisers...Synthetic DOT3/4 (I think Valvolene). DOT 5.1 is a different kind of fluid completely, isn't it (which explains why it's incompatible)? Isn't it the stuff that is completely hydrophilic and more compatible with high temps, but not as good at rtransmitting the force?
