- Also Works on AC Delco 172-1353, 172-1371

Works as it should, but I purchased a second one because the first one came with the tip broken off.

I didn’t get any fluid out of the front calipers. The bar on the inside of the proportion valve was shutting the front brake fluid off. This keeps the bar in the middle so the bar doesn’t move. I still don’t have a nice pedal but I at least have fluid coming out of the caliper!

Works great to center the plunger on your proportioning valve. Use to make sure it’s centered and also use it while bleeding the brakes to guarantee centering.

Easy to use . It did what it was supposed to do . Even tho it was made of hard plastic it did the job . It’s a very important tool for anyone who has a gm car with power front disc brakes ( mine also had rear drum )
