Thanks for all of the advice, just some more information as to why the PacBrake set up. I bought this coach in 2008 but it was a left over model that sat in San Diego for a year after being driven from Indiana. I am thinking the people who drove it from the factory might not have used the engine brake. I am thinking that was the main cause plus the lack of lubrication. I tried to buy the PacBrake lubricant locally at Freighliner or my local parts store didn't have it. It's available on E-bay;)
