PARKING BRAKE WOULD NOT RELEASE
Well, got ready to leave the rally at Tenn a couple weeks ago, and the parking brake would not release! it felt spongy when I pushed it down. Turned off the coach recrancked and still the same thing, so I call Troy, he says look at the pins in the slides and see if they are in all the way they appeared to be. So he guides me to the bay below the drivers seat. I locate the Big yellow air line coming from the parking brake and it runs into a part that sets right beside the norgren valve. It has a plug with two wires running in to it, you have to remove a screw to unplug it. This he says is a sensor that tells if the slide pins are closed and allows the parking brake to release. I unplug it and the parking brake release. so he says to take to Prevost the first chance you get. I had to get back to V.A. so have not taken it anywhere yet. Maybe a bad sensor or slide pins not locking all the way. I use dry graphite spray on the pins and such, any one had this problem hope its not major? Gary

Gary’s post has to rank high as a significant piece of information.
Our coaches as typically set up have a number of things that can turn a pleasant trip into a not so pleasant trip if they fail. If an inverter fails and we cannot get electric to vital items like the refrigerator or water pump, that comes to mind as an example of one of those things. Having an engine that will not start is another example. So is a ruined tire and no replacements available. Some are an inconvenience, some are crippling.
A slide malfunction that will not allow the coach to move ranks high as one of the things that can spoil a trip.
With the significant number of coaches with slides, and the various different slide manufacturers as well as various iterations of slides from the manufacturers we are all potential victims of a problem. Gary’s post has inspired me to try to learn more about my slide version and what switches and devices have the potential to make the slide system fail, and how I can overcome that problem.

Jon, Go to the Prevost site, look at slide pin sensor adjustment, The part I unpluged must have been a sensor override? Like you say at least it gets you going, but seems prudent to get it somewhere to have Prevost look at it. A bus garage would only deal with seated coaches I would think and not be familiar with our slide out system, all the more reason as you say to try to become familiar with it’s workings, guess I will be making a trip to Goodletsville!

I never have problems on weekdays between the hours of 8:00 and 5:00 eastern. When I have problems it is a holiday weekend so knowing I am never going to get someone on the phone I start out assuming it will break, and when (not if) it does what is my plan? I pretty much had it figured out on my 97, now I am working on how to deal with the new problems I can expect on the new one. We need a class to teach us all the little tricks and procedures.

Jon, I agree that would be great and I would attend who could put such a thing together? and where Gary
