I forgot to mention in the updates that I may not actually need a new master cylinder, but is not returnable, so I will probably use it anyway. When I hammered the brake lines shut, out of curiosity, I went in and pushed firmly on the brake pedal... It did not sink.

Driving to work today will be a sure indication of whether it needs to be changed.

Either way, booster is coming off, and pedal leverage will probably get changed.

P.S. Did anyone notice that the brakes on the front aren't vented discs? They're solid...wonder if there's a pumping loss advantage there, since they're not moving air through them like a fan?
