It's not true to say it no cooling system, as it was air cooled. Many Porsches have been air cooled and air cooling has much to recommend it.
Well I was only quoting from the blurb in the museum. Maybe they were referring to the fact that the air cooling was as good as useless? - I mean given the state of the rest of the vehicle, I suspect that the Trabant's air cooling system was unlikely to be to Porsche standards [;)]
I'm surprised those thorough Germans didn't spell "brakes" correctly.
Maybe spelling the word as breaks was a freudian slip [;)]
