I whole heartedly agree with Ed Holyoke about replacing the MIL-H_5606 with

the Mil-H-8328.  Being one of those who had experience with a brake fluid

fire while using the older MIL-H_5606, I never realized until after the

incident that its' flash point was just a bit above the boiling point of

water.    Fortunately I only lost a wheel pant an tube/tire out of the

incident.



I also replace the aluminum tubes ( the side of the right brake line blew a

chunk out and sprayed the hot rotor with brake fluid) with stainless steel

braided brake lines and replace the brake rotors with a set that had double

the thickness of the standard RV brake rotor.  Doubling the mass with the

same amount of heat effectively reduces the temperature of the mass.



The thicker rotors provided an unexpected side benefit in that brake fade

even after a hard stop is gone and the pads wear more evenly and last

longer.  



But, of all my changes the switch to the MIL-H-8328 is the cheapest and

probably the most effective in reducing probably of brake fluid fire.



YMMV

Hi Ed - thanks for posting.... can you post the part number / source / approximate $$ of the thicker rotors?



Thanks again,



dave

I think I might have missed something.  Why are so many RVs having brake 

fires, requiring the redesign of the entire brake system?



I have been flying my RV for 8 years with the brakes built exactly to the 

plans.  Just wondering, should I ground my RV and redesign the entire brake 

system?

I don't think you've missed anything.  And there aren't 'many' RVs 
	


having problems.  All it takes is a few.  Then add those Long EZs, 

Velocities etc. that basically started the plastic line implementation 

... and now you have a few more.



 From what I know, the problem arises when there's a long taxi with a 

crosswind .... the brakes get hot, the plastic gets soft, and it 

ruptures.  Have you just dodged the bullet?  Who knows.  All I know is 

that it's a weak spot, and I'm going to fix mine.

I really think that decision is up to you.  Do you like to gamble???
	




BTW, I've already replaced the plastic brake line between the pass and 

pilot side.  I don't understand why, on the high pressure side, he uses 

plastic from the pass side, then flex (that one I understand) to the 

firewall, then hard alum to the gear leg and then plastic to the brake 

cylinder.
