I'd definitely look at pain problems before presuming your horse is being a "brat". Putting a folded blanket under might help the situation, but it doesn't fix the problem of a poorly fitted saddle. Its best if you get a professional saddle fitter out to see what is going on with your saddle.
Also, if your horse has had a bad fitting saddle chances are her back is quite sore, so getting out a specialist, such as a chiropractor or a masseuse could really help.
I'd also look at getting her teeth done if you haven't already.
Obviously she has learned this behaviour, was she like that when you got her or has this developed? How long have you had her?
Personally, I'd look at some ground work, getting her to yield from pressure, teaching her that you are the boss, and teaching her what is expected from her. If you haven't already got a riding instructor perhaps you should look at getting one.
Just a note - the cantle is actually the back part of the saddle, not the front.
