Hi, so my dad and I started up the car for the summer and the brakes go all the way down like there is no pressure on the brakes. All we did so far was bleed out the brakes to let air come out and added new brake fluid. But still the brakes go all the way down. Please help.

Maybe it is the master cylinder.

Oh yeah, there are air bubbles coming out of the master cylinder where the brake fluid is.
