yup i have never had a failure doing any car this way......and the pusher calls out starting...3/4....then i crack the bleeder...1/2.....1/4...then i close the bleeder.....down.....then I tell him release and we start all over we do that about 10 times per caliper

Thanks, after I thought about it last night I realized the booster ain't gonna make the pedal go to the floor. I wonder though, if air in the system will cause the intermitent problems described above. Just seems strange that they work fine one day and then act up the next.. this is a daily driver, so it gets a lot of use.

Here's how finicky these things are...last week, I had a pedal to the floor scenario after several months of inactivity...I remembered that when I initially bled the brakes...my rear driver side had air, only that caliper...this last Sunday, I bled just that caliper again (seeing air in that caliper during Sundays bleed), and WHAMO!...great brakes again...I am deciding what to do about it..
