Ok one of my friends borrowed my rollerblades and took the brake off, I need to get it back on, problem is he lost the screw and I know there is some kind of screw or something that I need to keep it secure, I just don't know which kind. The kind of rollerblades I have are koho avec 5, I don't know if that helps, but yeah, I'm going to check at the local skate shop and see if they can't help me but if any of you might be able to tell me what screw/screws I might need that would be great, if not, thanks for your time, peace
