Default 94 Hissing Booster

Hissing booster & hard pedal began this morning.

I've heard it can be one of two things:

some sort of plastic valve which is easily replaceable?

defective booster (torn diaphragm)

Thoughts?

It's probably a cracked booster housing.
I did mine before for the same symptoms.
Make sure you torque the new one to the proper spec.
