Thanks, Richard. I will top up the fluid and give the capping diagnostic a shot. I was not present when the wheels were off and brakes checked, so I may have to personally check them during this whole process, but my mechanic is also the previous owner and a good friend. So I will rule out master cylinder, booster, etc. before diving into the rest of the system.
I have never had a situation where a dead pedal pointed to the booster. Usually a dead booster would make you have to stand on the pedal to apply brakes, do you think that would be the case here? Also, from what I understand, if it were a hydro system, losing the brake booster would more than likely be simultaneous with a power steering problem.
Anyway, as I know more, I will update here. Thanks for the reply!
