It can be tedious, but if your valve will not self center the you need to take the block

apart and clean it. ?You can reach down into the switch hole and center it yourself with a?

awl or other pointy tool. I have done this before.?

Best of luck

That sounds like a great tool for bleeding the brakes and keeping the proportioning valve centered.? However, that is not my issue.? My proportioning valve appears to be off center, and I need to center it.

Use a flashlight and look down the bore, you will see which way the valve has moved as

it doesn't actually move very far and you will see the depression that the switch sits in

on one side or the other. Put the tip of your awl in that depression and attempt to push

it to center. ?You will likely go to far and have to try again being slightly more gentle.

Good Luck

Although I am still in Florida for a few more days, i had a nice chat with David Hadley when he called to check on me. He had heard on the news that a twister was spotted near State College. He was unaware that we had moved from the State College area to Washington, PA in August.

It was disheartening to learn that he is suffering much back pain from a recent fall, so please add him to your prayer list.
