I have to agree with Ernest on this one.
After much research I found that Cleveland brakes have a similar warning that their seals are compatible with red aircraft fluid (Mil-H-5606).
 Originally I thought that any of the modern, high-tech brake fluids would be better but after reading the instructions I changed my mind and decided to use what is known to work. If you use other than what is specified and there is a failure, you can't blame the brake supplier and it may even invalidate your insurance (if you can get insurance that is).

Whatever you use, verify that it is compatible with the brake seals.
For instance the "General Wheel & Brake Information" document at:

http://matco.elixirlabs.com/catalog/index.php?file=catalog&uid=2192&prod_pcategory=77774&clist=0,77774&uid=2192

says:

"All o-rings in the brake and master cylinder assembly are buna nitrile
and are not compatible with automotive glycol based brake fluid. ONLY
red aircraft fluid (Mil-H-5606) or other suitable petroleum-based or
silicon-based fluid should be used."
