The story looks like a penny dreadful of “Russia is doomed” series.
1. There’s no info on that Russian slide about actual planes flying without any breaks at all. There’s a manufacturer defined minimum equipment list that allows planes to have some breaks (actual number depends on the type of a plane) disabled for, let’s say, 10 days at the most.
This is absolutely normal as planes cannot be serviced constantly (they fly back and forth, duh). As long as you don’t exceed the allowed number of breaks disabled, you’re fine.
2. The slide just warns about possible adversary effects (off-axis skid and longer landing distance) if some of the breaks are disabled. This is expected, somewhat corrected by algorithms, etc.

3. No one is telling planes to fly without any brakes.
4. There are different types of “breaks”: the ones used in a landing and the ones for an end-of-runway “stop” are not the same.
5. If the adhesion index is lower than required for the specific landing (weight, fuel leftover, etc.) even the brand-new “brakes” are to no avail. Again, another parameter out of many.
tldr; it is absolutely safe to fly those nine Aeroflot planes that — at the moment of the slide — had some breaks disabled (not to mention another thousand of other Russian passenger planes).

More importantly, there is absolutely no shortage of airplane parts in Russia — they’re just delivered in a more “wink-wink” obscure way.
I guess it’s just the same as there’s no problem there and in China to get modern GPUs that US “ordered” nvidia and amd not to sell :-)
Or mastercard/visa/swift “blocking”: even kids in Russia now have foreign virtual cards that are topped-up via p2p crypto in a matter of minutes so that one could buy anything digital (and physical via mail forwarders) online and rendering that great — mostly pr/perception based —“exodus from Russia” obsolete.
