Pedal foot pressures
 

I'm temporally limited in the pressure I can apply by my feet. What is the operating pressure for an eV-8 clutch on a '39 pickup? How about normal braking. Or said another way: I'm limited to picking up 25 pounds of stuff. Can I safely operate my 39?

As long as you don't try to pick it up! ;-)

Seriously, if you want to give it a try, and who knows if this is even a valid test, but you could go to the gym where there is a leg press and set it to 25 lbs and see how it is to move it with one leg.

As you know, I have a 39 sedan. It is a very easy car to drive. Your truck has the same chassis. Not sure if the rest of the running gear is the same, but it is an easy car to steer and operate.

YES!!! Milford. I was fishing for a Doctor Fordbarn to bless me driving my '39 pickup. My womens are getting anxious. Coming to CDC this morning?

Thanks Doctor

No idea what the actual vechile pressures are, but when doing brake calculations to select components when designing a system the max leg pressure used is 70 lbs.

Are you saying that after all this time, and after ALL the women's that seem to continuously hang all over you, that you don't have at least one weeman trained to chauffer you around in that rig? DD

If you are ok to stand from a sitting position, you are lifting almost half of your weight with each leg. Is the doctor ok with you walking?

Max clutch pedal operating spec is 27 pounds I believe....
I no longer recall where I heard or read this number and I also have
no idea if Ford would have subscribed to (what I'm sure is a fairly current
standard) way back in the 30's.

nitpicking.... mixing up pressure and force.

Ms.Sandy drives me to and fro to cardio rehab class Wonderful of her. My stick shift trio wait patiently in the heated garage. I get pressure and force if I threaten to drive an old car.
Merry Christmas .

A lot of pedal force has to do with the actual working of the brakes and clutch. I have a cousin who had a hot '62 Corvette with a STRONG pressure plate. That car was a bear to drive. My '63, with non-power drum brakes is a bear to stop.
