nema potrebe da se skidaju sve te plastike samo se skine kozica rucne kocnice, i odatle se vidi zuto dugme koje moze da se pritisne dugackim srafcigerom, podignes rucnu pritisnes dugme spustis i to je to zategao si sajle. there is no need to remove all those plastics, just remove the handbrake shrimp, and from there you can see the yellow button that can be pressed with a long screwdriver, raise the hand press the button and lower it and that's it you tightened the cables
not really, release cock behind the lever cant be reached by hand if tray is not as least lifted - specially if one of or both cables drop out of pulling shell at the end of short cable.
