M20J Brakes

I’m looking to buy new disc and pads. Anyone have any experience with the APS Blacksteel disc at all? From the description, it seems they won’t rust or corrode all. The rapcos are only treated on the hat portion, per the description. I have a shade hangar in Florida so I’m definitely in the corrosion environment. I fly once or more a week so that negates some of it.  Not sure which pads are the best but people seem to say Cleveland? I’m guessing you can mix and match disc and pad brands without issues. Also it seems all the pads AS says are compatible with my plane, are organic ones. What’s the benefit or difference in organic and metallic ones? Thanks!

They work fine.

However any disk that doesn’t  rust won’t work as well as one that will. Without getting into exotics it seems that for converting kinetic energy into heat nothing beats sintered iron, which of course rusts if you look at it sideways.

However unless your the guy who heavily uses your brakes I don’t think it matters, either SS or sintered iron will work fine.

Often aircraft brake pads are offered in organic or metallic, often the words heavy duty go with metallic. I use organic, they don’t last as long but work better when cold and don’t wear the disk nearly as much as metallic, metallic lasts longer largely because they put much of the wear on the disk.

Sintered iron would mean it was pressed from hot iron powder.

Brakes are cast or forged iron or steel.
