New brake bleeding tool
This is one of those "why didn't I think of that" tools.
One frequent problem when bleeding brakes on dual circuit systems is that the piston in the differential pressure switch can get forced all the way to one side or the other and block that brake circuit from flowing. This problem is compounded if you have an original cast iron combo valve that might have rust in it, as the piston gets stuck.
PerformanceOnline.com has just come out with a clever tool that simply screws into the distribution block or combo valve and locks the differential pressure switch piston in the center position while bleeding the brakes. You simply unscrew the plastic switch body, temporarily replace it with the tool, and bleed the brakes. No, brake fluid will not leak out, as the space around the piston is dry and sealed by o-rings. If you do get fluid, the valve is bad anyway.
Just remember to put the switch back in when you're done. $8 online.

Evidently they never learned that "cutaway" is one word.

great idea for a tool, and modestly priced

While I thought the tool is cool when you first posted this and have recommended it or similar since for the newbies. I still in all my 40+ years of doing brakes have never needed it to bleed brakes and I still do it the old fashioned way with a my pretty helper to pump the pedal.
