sounds like ABS sensor , check master first ,the way I do that is in park and apply slight pressure to the pedal and if it makes it's way to the floor thats a sign of bad master .I'm not a technician but if your pedal can go to the floor that does not sound safe and perhaps a technician shopuld look at it .

It means there's air in the brake system, u need to bleed the brakes one wheel at a time. Have someone pump brake pedal 3 times, hold it pressed while someone turns the bleeder fitting loose, once it squirts fluid out, repeat 3 times on each wheel, refill master cylinder as u bleed each wheel and keep master cylinder closed while bleeding system
