leaning after shut down and brake problem

[edvanland]

OK on our MCI 7 after it has been shut down over night it will lean 4 inches on the left side. The air gauges on my leveling system show 80 pounds and the bags seem full. The air pressure builds up to 120 lbs and is a new compressor. Having problems with my brakes after this trip they don't want to stop the bus. Backing down the drive they would not even hold the bus when I put on the emergency brake. Have a new pre set 65 pound pressure valve I will be putting on one of the front air tanks I just received from Luke. Please only give pertinent answers. Any suggestions will be appreciated. As far as the brakes go there are no oil signs on the back side. They are all adjusted correctly and have very little wear on them I am going to go to a softer lining when I pull the shoes. I will also replace any parts of the braking system that even looks like it might be bad. Thanks in advance.
