Re: bad brakes
DON'T DRIVE IT UNTIL YOU FIX IT! Redesign/adjust the pedal lever,
booster, and/or master combination!

You have air or maybe dead wheel hoses that are ballooning. My bet is
air.
Did you bench bleed the MC?
Was the proportioning valve ever empty of fluid? If so there is likely
a pin in the end of it that needs to be held or pushed depending on
version to lock the guts so you can bleed the air out. If you don't do
this, that valve will never get the air out and work and you can
compress the pedal down if you really push on her.

Re: bad brakes
My Jeeps brake booster died with only 700km on her.
Was heading out on my first camping trip (mountains in BC near
Hope...awesome).
Luckily I was stuck in a traffic jam on the highway and wasn't going faster
than 15kph.
First thing I noticed was my RPM's kickin up when I hit the brakes and found
I was having trouble stopping.
I actually had to pull myself down with the steering wheel and couldn't
stop. Had to downshift and use the E-brake.
Anyhow, I was close to a dealership and luckily the salesmen were still
around (was 8pm or so).
they were cool enough to give me the loner car for the w/e (damned frickin
NEON car...got teased bad about that!).
anyhow, they fixed it and it was covered, of course. the guy told me that
it reverted to manual brakes....I kinda laughed. I've driven some manual
brakes before and that wasn't what they reverted to....could've stopped
better sticking my foot out the door!
