Q: ABS and Brake Light are on. on 2003 Chevrolet Trailblazer

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have a 2003 Chevy Trailblazer and my ABS light and Brake light came on after my dad replaced my breaks several months ago. My brakes work fine, and when I set the parking brake, the Brake light goes off, but turns back on when I release it. I have seen lots of postings for this for Trailblazers, but not really an answer about whether or not it is a big (ugh, expensive) problem or a cut wire, sensor problem, etc. I had my tired repaired (slow leek) 2 months ago and had them look at the cause of the problem, the mechanic said the brakes looked great and he didn't see any problem with ABS, but to be sure I would have to take it to the dealer, because he wouldn't work on the "brain box" (whatever its called)due to a lack of knowledge about it. Any help?
