as far as i can tell, the contract is enforceable against your friend. the general rule is that not understand the term of the contract is not an excuse. of course, it would be a different issue if you can prove anything like fraud, duress, or adhesion, which is unlikely.
does your friend understand the meaning of 'co-signing' a loan? if your friend does not want to be responsible for the loan when this sort of thing happens, then he/she should not co-sign the loan. from the bank's point of view, the whole point of having someone co-sign the loan is to minimize the risk like this.
