I have a 90 Prism that had the same problem. There is a platic spacer on the brake arm the crumbled with age. it is very hard to see where it is located. I glued a penny and a dime ( the thickness of the space ) to the brake arm....problem solved.
I don't know for sure about the Geo although we do have one but I just went though a similar situation with my Toronado. When I replaced the brake power booster my lights wouldn't shut off. I got under the drivers column and realized that the switch had been moved while moving things around to get the booster out.
On most cars there is a switch (with a little button that moves in and out) that must be up against the brake arm. If it is not up against it, the brakes are reading it as on. When the brakes are depressed up towards you, it depresses the button and registers as being free.
Hope that helped.
Start by removing the connections for the cruise control and brake lights, then remove the bolt that holds the switch to the brake pedal. Once the brake pedal is loose the switch is held on the brake pushrod by a bushing with nylon retaining washers. Carefully remove one washer and slide the bushing out, the switch can now be removed from the pushrod. Installation is the reverse; line up the hole on the switch with the hole on the pushrod, make sure the tabs for the cruise control and brake lights are facing properly. Reinstall the bushing and replace the other nylon washer, replace the bolt and tighten. Lastly connect the brake lights and cruise control.

The obvious would be the bulbs are burnt, then look at the fuses for the taillights, and then the wiring. The holders where the lights themselves plug in are bad sometimes; you can get them cheap at a pick-a-part yard.
it may not be you ignition relay, but your alternator.
you can bleed the brakes all you want but with that wheel cylinder leak its all going to leak right out and equal...thats right you guessed it a soft pedal in other words you are getting almost no brakes in the rear! DANGERRRROUS!
because you ugly alternater.
The running lights have a bad ground.
check the fuse for the brake lights, they have thier own. also check the brake light switch at the at the top of the brake petal

Check the switch at the brake pedal .
I'm not a mechanic but I would start by checking the brake fluid level in the brake master cylinder in your engine compartment
Check the wire which is going inside of the trunk hood to the brake lights.
Blown bulbs, blown fuse, broken or out of adjustment brake light switch.
check the brake light switch on the brake pedal
Sounds like the main ground wire for the rear lights broke or rotted off the frame.
burnt fuse ... tail lights are on a different circuit than stop or turn lights
