Here is the master cylinder I have Master Power Brakes - REMOTE FILL POWER MASTER CYLINDER WITH PLASTIC RESERVOIR
Based on your response I went out and measured the pedal heights
from the floor...
6 inches high before pumping it.
first pump, it hits the floor
after a couple of pumps it builds resistance and stops about 2 inches from the floor
when released it goes back to 6 inches from the floor...
