Afternoon,
When we were in the Florida Keys recently and getting ready to leave the parking brakes wouldn't release.
I had drained down the air suspension and cycled the brake pedal to bleed the air faster after we had arrived and set up two weeks earlier.
When we got ready to leave I started the motorhome and let it air up but when I pushed the brake release they wouldn't let go. If it hadn't been for a kind person at the campground we were at then I think a call to Coach Net and possibly a tow could have been in order.
I have to admit I don't think I would have done what he did which was cycle the brakes several times let it air back up and applied the gas. Finally the right side let go but the left side was still holding so much so that the left side tires actually spun in the gravel. It finally let go but scared the crapola

out of me. I don't think I would have ever applied that much accelerator.
Anyone know what may have caused the brakes to not release. The actual parking brake air valve that gives everyone problems was replaced about two years ago and I haven't had any problems with them not releasing or any hint of a problem. Several years ago this same thing happened but very briefly and I was able to just apply the gas and they released. Didn't think a whole lot more about it then. This time was a whole different strory
Only thing I can think of is maybe I didn't let it air up till it reached its set point and blow off and possibly maybe I applied to much grease to the slack adjusters or something when I greased before we left.
If anyone has any ideas then I'd like to here cause I don't want to go through that again.
Thanks,
