Disc Brake Assembly

[Reccius]

Hi, some quick background info;
I have 2007 giant with the basic mechanical disc brakes installed, and recently discovered that the skirt protecting the spring inside the brake mechanism had become dislodged, allowing dirt to coat the spring and making the brake unusable. After taking the whole thing apart and cleaning it thoroughly, I was unable to reassemble the mechanism. It seems fairly strait forward, the only parts are the spring, the rubber skirt, the mount and a bolt. My only problem is that after 3 hours of the messing around, I am still unable to assemble the mechanism. Is there a straightforward explanation that would allow someone of very limited mechanical knowledge to repair the brake? Or have I managed to screw myself to the point that I need to buy new brakes. Thanks in advance for any help.
