If it rusted through in one spot the rest is probabally pretty crusty aswell, best way to check is to get under the car and check for any other small leaks or anywhere rust is flaking off the line. It may just be one spot that is rusted through and you will be able to patch it with a new piece of line and fittings, but if the rest of it isnt looking too hot replace the whole thing.
I ran into the same problem this spring with my fuel line, I thought it was just one small leak but the entire line was toast.
I'm not sure how the brake lines are routed on your car but on mine I know the brake line runs under the carpet and out under the back seat if yours is the same you should be able to just replace that section running from under the seat to the hose.
