It's the combination of width and tyre compound that gives you braking efficiency. Without ABS, wheel lock is impossible to prevent, but by increasing the contact patch, you can reduce your chances of wheel lock up (under similar conditions).
Just make sure you don't use, too big a contact patch, as that will also increase your chances of aquaplaning.
But, if someones facing probs with weak brakes, then wider tyres maynot be that helpful. You'l have to get your brakes improved first.
