brake treadle

[gasparillaglass]

When I push in on the brake treadle without motor running the
presure
drops steady and i would say rather fast .
When I run the motor it builds up
I have to put her in a high idle to get it up to release the spring
brakes about 110
from what I remember before I had the oil pan gasket replaced it
didnt do this
anyway I guess the big question is where is the air going??
anyone have any adea??
thanks to all
heres another one he he
also after the pan gasket was changed .
When I load up my air spring everything is good without dumping the
air bags and just putting down the leveling jacks I loose the back
right air in the air bags just on the rear right side not in the tag
