Where is brake fuse located in a oldmobile alero?

The brake fuse location in an Oldsmobile Alero isn't standardized across all model years. It could be in the underhood fuse box or the interior fuse panel (often located under the dash, sometimes in the glove box or center console).

To find it, you must consult your owner's manual. The manual will have a diagram showing the fuse box layout and clearly identifying the fuse for the brakes (it might be labeled "Brake Lights," "Stop Lamps," or something similar).

Without the year and specific trim level of your Alero, providing a precise location is impossible.
