Subject:Brake Pedal "Thud": Video (youtube)

Hi all.

My concern: internal leak in brake MC.

Video shows: Engine cold, "thud" heard (booster has vacuum) Vacuum
dissapates, hard pedal. Engine started, pedal drops (normal). Last
portion, thudding easier to hear.

Video not loud.

Does this indicate a failed or failing internal seal (causing internal
"leak") on MC?

Pedal NOT hitting the floor. Booster with vacuum, I can push pedal by
hand to "thud" (stops). There is 3" between pedal arm and floor

Thanks,

Neil.
