Brakes smell like a relatively crucible ride

Hello, I just drove about 30-40km, was a country road/city mix, in the middle of the ride I noticed that it smelled a little messed up, but after a short time it was away I thought nothing about it. When I arrived home the smell came back, cuckolded in the engine room but there was no smell to detect. Then I noticed that the front rims were already very warm, because I was involuntarily relatively strong from 100 to 0 brakes (but no full braking) I thought g gf the brakes are very hot and warm the rims with it. Then I checked the rear rims, and at least the right was already very hot, and also the smell came exactly from there. What can that be? Does the wear of the brakes appear like this?
