The brake is going to the floor.
Hello. I believe there is a leak in the braking system somewhere, which would cause this problem. It is also possible that there is a master cylinder leak, a leaking brake caliper, or a leak in a brake line, which would cause the brake pedal to go to the floor. It would be necessary to have the entire brake system checked by a certified technician in order to determine what is leaking, and fix the problem you are having with the brake.
