Pressure/pedal travel brake pedal

Since my question went down to other places (the big question-collecting thread), now again separately. When braking I have a “comic” resistance when tapping the brake pedal (perhaps 0.5-1cm pedal path). I can’t describe it better, but it’s not like the rest of the pedal path. If I then completely release the pedal and use it again after 2-3 seconds, the feeling is gone at the beginning and it feels constantly the same. After a short ride it’s as usual again. At the first brake it’s a little “different”. Did someone have something similar? Must soon go there, because my switch for the seat heater is stuck behind but wanted to hear before, whether it is imaginable or not.
