What would cause the brake light on a 1997 Mercury Tracer to stay on without touching it?

Your brake pedal may not be touching the sending unit to turn off the brake light. Try having somebody look while you pull up the brake pedal with your foot. You can adjust the unit to be closer to the brake pedal. There is no room to work, so have fun. There is a small plastic disc/spacer between the brake pedal arm and the brake switch that often fractures and falls off. It is about the size of a nickel, and has a small post attached to it--costs about $3.00 at a Mercury dealership.

1997 mercury villager what causes the brake pedal to go to the floor when there is no ABS light?

A brake pedal going directly to the floor is a sign of a few things. First, you are in need of brake fluid. Second, the brake pads are probably almost worn out. They may be worn out past the point the ABS light would be active. The ABS light may also be burned out.
