DO NOT USE 5.1  ... meant to say:
The brakes used are aircraft by either Matco or Cleveland and there have been no issues using the DOT 5 with them (that I know of.)

Velocity calls for using DOT 5 (Not DOT 5.1).  Velocities use this because the master cylinders are automotive and are not compatible with the 5606.  The brakes used are aircraft by either Matco or Cleveland and there have been no issues using the 5.1 with them (that I know of.)

John, I switched from the typical aircraft 5606 brake fluid to the new spec Mil-PRF-8382 brake fluid which moved the flash point from around 240F to 440F.  The new stuff is 100% compatible with aircraft brake components and can even be mixed with the older 5606 with no problem - other than the mixture will have a flashpoint somewhere in-between the two.

But, others have reported successfully using some DOT approved (Silicon based I believe), but be careful - some of the Automobile type  brake fluid is supposed to be incompatible with aircraft brake components (the seals I presume) and can cause the assembly to malfunction.

Ed, I'll take the weekend theory, it will take the group 6 months to digest all that info you exposed them to, this week.  I'm getting the boot cowl painted and hope get  the final instruments in next and go for the big first start next weekend.

       What brake fluid is nascar using or perhaps Lynn?  I know there was much discussion on this awhile back and we don't need to wade through it again.  I will post some pictures midweek when I get everything secured, firewall forward.  JohnD
Lockheed 550. DOT-5 compatible. 550 degree wet boiling point. Some big parts stores and most hotrod shops/catalogs. A must with carbon brake pads.
