"Often when the big Il-76 landed on the 2000m rnwy, the brakes became overheated. The Swedish CRFF-team (crash, rescue and firefighting) often had to cool down the brakes with water"

This has been bothering me ever since but I saw no threads on the subject. I've always been taught that since brakes are metal, when they are heated no fast coolant should be used as the sudden contracting could explode. Magnesium usage in brake material would add to the problem if that's used.

With that in mind and seeing the thin foam on top of the fluid. What was really used? Or am I completely wrong and some areas actually use water.

Looks like some type of foam to me, or even soapy water (guess that's not likely though!).

Also, one of them tires don't have much tread left on it!

An almost identical thread was started not too long ago...I would have a quick search if you want to read more people's responses!

I guess that's what happens in the end, you start thinking about the beginning.

Does the IL-76 have carbon brakes? I don't know if that makes any difference.

While I was in A&P school we were told that the only thing you use on a hot brake is a cooling fan if anything at all, its not just the brake that gets hot, its the wheel and tire too.

If its actually progresssed into a fire we were told of a special extingusher filled with a substance called "metal X", it just forms a coating to smother the fire and has no cooling effect at all.

Not sure what happens in other countries, but we were always told anything that causes rapid cooling could be fatal if it blows.
