The parking brake can cause the Brake warning light to come on. You can disconnect that switch (temporarily) and see if that cures the problem.
If not get it checked out by a professional quickly before you have an accident.
ABS is nice to have, but not necessary. If you don't want to see the ABS light, just disconnect the fuse for it.
