Need Help ABS INOP+BRAKE lights on!!

Can't find the problem? Anybody have any idea why these lights would be on? The car is a 93 - and has been sitting with a dead battery for most of the winter.

Thanks for the help

Press down firmly on the brake pedal and see if the brake light goes off. Also check the fluid level and that the parking brake handle is all the way down. If it's not these things, a bad ground connection on the ground post on the passenger inner fender liner (next to the red plastic positive post) could be the culprit. Disconnect the battery, remove the terminals from the ground post, remove the post and remove the paint from the fender around the post hole). Then reconnect everything.

could also be the abs relay in the fuse/relay box in engine compartment.i pulled mine out because i think the abs motor was going south and i have the same lights on.

Also check the ABS sensors, if they are dirty clean them with brake cleaner. This happened to my buddy a few times, easy fix but annoying.
