Booster fault will not lead to dropped pedal quite the opposite.

If pedal drops without leaks somewhere that usually means seal on the MC FAILED and fluid is just going around the piston.

The confirmation is to detach the two lines coming off mc and plug the outlets. If you can push the pedal down at all the MC failed.
