Weird Sound - Brakes

[stever1000]

I just replaced the master cylinder and some brake hoses with stuff from Camelback Toyota.

I am now trying to bleed the brakes (already bench bled the master cylinder on the car) and I noticed a weird air sound, like air moving when I press the pedal.

Please check the video out, you can hear the sound mid way through:

Vacuum leak. The pedal should firm to the point that it cannot move when the engine is off. Or your brake booster is shot.

Prior to changing the master cylinder I was able to build pressure pumping the pedal so I thought the booster was ok

I didn't have the master cylinder completely level when I bled it so I took it off the vehicle and will try again

I should have mentioned when I made the video fluid wasn't moving from the resivoir so I thought air was trapped at the far end....
