Moved from another post, thought maybe no one saw it as there were no responses to this particular question. I noticed today, when stopped at a light I could hear the electric motor for the brakes...
All of have been most helpful, not to mention relieving my worries about this part of the braking system. The address to read about the hydroboost was very informative, I enjoy reading it.
So many times I've needed answers to questions and no-where to turn but RV.NET, it has never failed me.
