Why is the brake light on after replacement of brakes?

Hello, I would have a professional evaluation performed as soon as possible. Brake concerns are a major safety issue and you definitely do not want to lose your stopping ability from some unknown cause. A red brake light indicates a safety issue is present. This could be a problem with the parking brake mechanisms, air in the brake lines (including the ABS system), a master cylinder issue or a brake pedal travel issue.
