Check the 15 amp fuse in location 3 of the dash fuse box if fuse is good then you can remove the brake lamp switch and connect both of the terminals together to see if the brake lights come on if so replace switch if not verify to see if bulbs have good power and ground then go from there. Here is a wire diagram and picture location of brake switch. Let me know if you have questions. Thanks
