Can anyone interpete me with this TÜV Private report?

Hello, I got this report today for a car that is privately advertised. I unfortunately don’t understand the things with the brakes. In addition, 2 summer tires drove in. Can this be a bigger problem? The tires were bought in 2021 and were driven about 23000km. Winter tires, which are on it also have different profile. But probably not driven in. At least there is nothing in the report. Is a Seat Leon, BJ 2016, 100000km, 116PS.
