Need your input on a strange issue with my CX77 brakes on my CX bike.

Ocassionally under hard braking, it just locks up and doesn't release anymore. So far it happend only on the front wheel. When it's locked up, I have to undo the cable and manually twist the "brake cylinder" back all the way to "unlock" it.

So far, I have no idea why this is happening. Anybody else uses the CX77? It seems to be something of a rarity.

Cheers, Philipp
