I bought this tool and I'm told it should will re-center the valve in the casting without needing to remove the casting from the frame, just remove the pressure switch (may be harder than it sounds) and screw this in its place. Once valve is centered I think you can leave it in while bleeding to make sure it does not move due to pressure differences while bleeding.

I would have thought you would need to use a small screwdriver or pick to move the valve prior to inserting this but maybe not?

I believe the piston is tapered inside.

So the tool should self center when screwed in due to the taper?

Hopefully...
I would put a mild radius on the very end, so it isn't such a sharp edge.
Yes, leave it in until done bleeding.

So............I had some time to mess with this today and ended up taking the valve off again this afternoon (took another brake fluid shower) because I could not remove the pressure switch while mounted in the car, regular socket was too short - pressure switch terminal poked out the top and deep socket was too long to get ratchet to work as brake lines interfered and zero room to swing a wrench of any length. Once off, the pressure switch came right out - but if I am looking at the internals correctly the piston needs to move in the bore to get the port to a spot where the centering tool will work? Does not appear to be enough room to use a pick to move it either.........what am I seeing here? Do I need to remove the nut on rear line port to push the piston to center? Somewhat hesitant to start taking things apart on a freshly rebuilt valve and create other problems.

Time to turn on the Illinois game to see if they can beat Iowa to be Co-BIG10 champs......

Thanks
