Brake Pedal to the Floor

#1

2002 3500 Express van, 15 passenger. The brake pedal intermittently goes
to the floor. The mechanic put in a new master cylinder, but it doing it
again 2 days later. Any idea what is going on? My guess is the ABS or
hydraulic booster.

Are you using the correct brake fluid?

Is there a leak?

Did you bleed the ABS per factory service manual instructions?

Don't know if they did or not.
