Had a new parking brake valve installed last week to replace one that had a large leak. The new valve often fails to release, acting as if there is not enough air pressure. After a few tries, it will release. At the time I had the valve replaced, the brakes were also adjusted. Wondering if the two changes are related. It might just be my imagination, but it seems as though there is a lot of resistance to finally get the coach rolling after the valve does actuate.
