I am in agreement, Bill.
 
I've found several more brake fire incidents - in experimental (another RV-8), GA and Airliners (small ones).  No doubt in my mind at this point there is little reason I can think of for using the old standard 5606 with a flash point for from 187-240F (depending on which formulation).  The new stuff H-83282 has a flash point of around 440 F and as several have mentioned there are brake fluids out there which simply won't support combustion.   I believe Lynn pointed out that the temps of brakes exceed 400F by a considerable margin - so even the new substitute for the 5606 is no panacea - but still better than having a 200F fluid in my opinion.  Of course, the best prevention is not to have any leaking fluids - but, then who plans on having a leak.{:>)
 
Right main gear rod removed yesterday and sent back to Van's for straightening - so in addition to the $200 for replacing tire, brake line and pads, there will be the cost for straightening the gear rod (est $180+) plus the cost of a new wheel pant and hardware plus painting.  All in all the total cost will approach $500 or more all because the $2.00 aluminum tube brake line broke.  All brakes now fed by stainless steel braided, Teflon-lined genuine brake lines.

Marc,
A rather cavalier reply. If you could, wouldn't you carry a NON-flamable (externally at least) fuel? If it was possible I'd make that change in a second. We have a running discussion about engine fires and controlling them! Why on earth would you want brake fluid that burns EASILY?! Compatibility with aluminum has been the only reason I have heard. This is a non issue with modern fluids. Ed Anderson has had a brake fluid fire. John Randolph who just did a round-the-world flight in his RV-8 was stranded in Thiland for 3 weeks because of a brake fluid fire on landing. These are fires I can mention off the top of my head and I am sure with little digging I could find more. This is a completely UNNECESSARY hazard. I will try to remove as many of these as possible.
