Another word of caution: I have a Howe clutch pull-type slave cylinder and DOT 5 leaked past all the seals. I called Howe and they said "our seals are not compatible with it".

Would have been nice if the instruction sheet had said so! $19 for a rebuild kit, a cup and an o-ring. Then they had the nerve to charge me $14 shipping on something that fits in a $1 first class envelope. I flushed the master and line, put DOT 4 fluid in the clutch system and no problems since.

Still have DOT 5 in the brakes and no leaks anywhere.
