Brian,

Thanks for posting you are OK, and back in action. Always good to hear a “fixed” on the I Need Help thread.

You have me thinking. This is the second time I know of that one of those plastic spool pieces in the relay valve failed leaving the coach stranded where it sat. After the first one, I started carrying the replacement part. Now after the second failure, I think I will go ahead and replace the spool piece as a preemptive strike. Better here at home than the side of the interstate in Wyoming, or worse Atlanta.

For those who may decide to replace the spool piece, remember that the spool piece is part of the brake air system. All air pressure including the brake tanks must be bled before removing the circlip, otherwise you will have over 100 psi of pressure on the spool piece. The spool piece looks to have over a couple of square inches of surface area, meaning the piece will have over 200 lbs of force behind it if you don’t relieve the brake tank pressure. That would leave a mark when it hit you.

And always, support the coach when you are under there.
