The booster is a mechanism that uses vacuum pressure to take the force being applied to the brake pedal and amplify it.
Passat brake pedal goes to floor.
I pump it to slow the car then the minimal resistence the brakes give with the pedal to the floor is enough to stop the car.
Low brake fluid level.
Check your brake fluid.

Here s an additional reason a brake pedal could go all the way to the floor.
My guess is they didn t rotate the rear pistons when compressing them.
Within about six blocks the pumping method stopped working and now i have only about 10 brakes if i hammer it.
A bad brake booster.
My 2 0 started having an issue awhile ago where under steady pressure the brakes would slowly lose grip and the pedal would drop to the floor.
If the booster is bad then the full amount of force needed to activate the master cylinder and pressurize the brake fluid isn t.
Anytime you have a brake pedal that goes to the floor raise the hood and locate the brake master cylinder s reservoir.
