NEED HELP! Wheels don't fit!

[transio]

Bolt pattern is fine. Backspacing is fine. Can't get the wheels on though. The hub (#1 in diagram below) and cap (#6) are too big in diameter, though, and stick out too far. The wheel gets stuck on them and won't go on all the way.



I need some advice. What can I do to make the wheels fit? Do I have to replace the entire brake system or is there just a flatter hub that I can get?

PLEASE HELP !!! Any advice or info is appreciated !!!

Thank you
