can not get brake pedal to not go directly to floor

Hello,

The brake pedal can go to the floor due to a leak in the system, as well as air in the brake line, low on fluid or a bad master cylinder.

VW does recommend that the calipers get pre-bled.

I have attached the factory recommended brake bleeding procedure below. Take a look at it just in case you might have missed a step.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
