And I'm wondering if there are engineering whistleblowers on this site that I can chat with.

Spongy means air in the lines which means the lines need to be "bled." A hard pedal with decreased effectiveness sounds like your brake power-assist is failing. With the engine off you should feel this effect after pumping the pedal two or three times. A hard spongy pedal seems contradictory.

Very few states give pedal force in lbs vs. pedal deflection standards, which I find rather unscientific. IMHO, the middle 1/3 of pedal travel should go from no braking to max braking, for a 100 lb. driver.
With a clutch, the middle 1/3 should go from no engagement to full engagement.

You're welcome! :)
