I brought my new 7.2fx home today from the bike shop. I had to take the front wheel off to fit it in my car. They showed me how to put it back on, but when I got home it became impossible for me to do it correctly. My left brake keeps collapsing onto the rim and I when I hook the brakes back up it is offline and the front wheel is stuck with the brakes locked down.

Any suggestions. This is my first bike and I'm not very mechanically sound.

Thanks
