Answer: Some use ATF, most prefer to stick with aviation grade 5606H. Either should be compatible with synthetic rubber seals.
Re: Aircraft brake fluid?
You could probably put Marvel Mystery oil in there, and it would work fine
(plus smell good) ... I don't think these brake systems are that picky to be
honest, as long as the seals don't melt ...

Re: Aircraft brake fluid?
Unless you're a chemical engineer, I wouldn't want to guess what's compatible with the seals in your brake system. Use 5606 as it's called for and you won't have any problems.
As much as I've been using lately, I just bought a gallon from Aircraft Spruce and it should last me a lifetime.
Cheers,

Thank's for all the replies. The reason I brought it up, is that I suspected it is like a lot of other things, In that it is the same cheap beer in an other bottle. I fear that when the word aircraft appears anywhere on the label,it usually costs 3 times as much.Dutch
Re: Aircraft brake fluid?
There are definitely areas we cans save $ on building our planes, but this wouldn't be one that I would choose. Brakes are one of the things I want to work properly with out any doubts. You don't want you brakes to fail at an inopportune moment, especially if the third wheel happens to be at the back of your plane.
Aircraft Spruce has a quart of Philips brand 5606 for less than $7. That should be enough to do your entire brake system. It's not worth the $4 you MIGHT save here.
Re: Aircraft brake fluid?
I concur Phil, especially with the third wheel is where it belongs. You could have some serious :eek: aaaw cr@@ moments!
Re: Aircraft brake fluid?
Just FYI, the 5606 is different than ATF fluid: The 5606 is a high quality mineral based hydraulic fluid. ATF is also a mineral based fluid with different additives for automatic transmissions, such as friction modifiers for the clutches, but some times is also used as a hydraulic fluid. It is just not optimized for hydraulic use as the 5606 is.
Re: Aircraft brake fluid?
A little late on the reply, but I was just looking through the MATCO specs and they indeed do authorize DOT 5 brake fluid. All others are not usable due to incompatibility with the seals.
