Answer
Hi Steve -

Looks like your mster cylinder went out. There are inner o rings and seals within the master, so the fluid passes through them, bringing the pedal down. Replace the master cylinder, and you should be fine. I recommend that it be bench bled before install.

Hope this helps -
Happy new Year -
aloha
