An aircraft can be stopped with reversers alone
Just a point of interest. If you have no brakes for what ever reason, and have only reverse thrust available then if you just manage to stop right at the end of the runway with full reverse still applied, consideration should be given to cutting the engines while in full stopped reverse.
The reason being if you cancel the reverse quickly when stopped, forward thrust caused by the engines winding down (no brakes, remember) can cause you to start moving again.
