How much loose/free should be front wheel with disc brake when I rotate by hand?

[yami]

Hi my friends;

Today I realized my only 400km driven, 1 year old TaoTao 50cc front wheel is not that free and when I rotate by hand it barely turns one round and stops.

Just like feeling that brake pads are somewhat touching disk.

I drove it without using front brake and it somewhat get hot.

What should I do? How can I increase space between pads and disc then they do not touch disc??

Thanx
