How to reset brake warning lights?

Hi all! I've got Olds Cutlass Supreme '92. It was sitting for a while on the seller's driveway and rear brakes needed cleaning and lubrication (were stuck on rotors because of rust). I did it myself and it works just fine now but I still have warning lights for Antilock and Brake on my Analog Cluster Instrument Panel. How could I reset it, so lights will go away?Someone suggested just disconnect/reconnect the battery for a few minutes and after it alarms will go away. Could anyone confirm it, please?

Thank you in advance.

Is your brake fluid up to level, that will make light come on if not filled correctly.
