You may have a point! Whenever I have my cabin heater on, the cabin temp at my feet is about 170°F. The rest of the cabin is just about 20°F higher than the outside. I don't have passenger brakes so the brake hydraulics are all by my feet. Increasing the temperature this much at the hydraulic reservoir could pressurize the system.
I still don't understand why the low side doesn't stay at 0 PSI. After all it went to 0 when the gear lever went to the up position.
