Right brake handle stuck

[urforgetfulbird]

To anyone out there who may have some advice, my mountain bike handle is stuck.<br />
I checked the brake tension and it seemed to be o.k.<br />
Is there anything I can do to fix it without taking it in?<br />
Any help would be greatly appreciated.<br />
Thanks

Remove the cable and housing from the brake as this could be seized.<br />
This will also show if it's the brake lever.
