so out it was raining out all day today and me and my friends had reliazed that there was a very large rainbow puddle under my vehicle in multiple different places i went. this hasnt happened till about a day or two ago but my brakes go all the way to the floor before anything happens and they would stay in place but now i go all the way down and sometimes they just give out. so I'm guessing i have little to no brake fluid. the puddles came from the middle of the hood on the bottom what brake lines should i be checking for spot? or could it maybe be those rubber hoses from the lines to the calipers
