DOT 5 Brake Fluid in a J

[Captain]

Do any of you have experience using DOT 5 brake fluid in a J's brake system?

Hi Captain

 

I was confused about the service manual saying ONLY to use auto dot 4/5 brake fluid and Matco saying otherwise. What I found out that Jabiru changes the standard Matco master cylinder rubber seal to be able to handle auto brake fluid. I added the auto dot 4 which was what is in the S-LSA when I got it and have no problems. Be careful not to get any fluid on the paint as it will eat it away and make things look crappy.

That is why I have gone with dot 5. It doesn't wreck the paint if you have a leak or a spill ...... and that is why Harley go with dot 5 for their bikes.

 

On any aircraft just think about a brake fluid leak while in flight. It would possibly be carried back all over the rear end.
