Anyone know the working pressure of our brakes? How much pressure are the lines under when standing on the brakes?

Depends....

....on how little runway is remaining...

(Sorry, couldn't resist! Good question - I'd like ot know the answer myself!)

Hard to answer exactly

I'd wager it's somewhere between zero and 2000psi....

Seriously, master cylinder piston size, pedal lever ratio and pucker factor, per Ironflight, all factor into the brake system pressure.

An example would be for a 5/8" piston with a 3:1 pedal leverage and a 200lb man (100 lb per pedal) lifting himself out of the seat. This equates to aproximately 1000 psi. I don't have the dimensions for an RV at hand, so YMMV

Brake Line Pressure

I suppose I could go through all the math, or one the other hand, probably break out the specs on the brakes and see what they say.

Hummmm.
