i got a whole bike with an INTER 4 for 60eu... but the brake is pedal operated... and i had a bit of a sticky prob, but i just cleaned it (with out taking it apart) real well with degeasers and then hit it with WD-40... and then dryied it all up with a cloth, and its much better now...
oh and the brake squeals like a b!t$h when im going real fast, and slow down fast... downhill...
pics???
