I installed this assembly for the stock gauge in my grandson's 2006 Toyota Avalon a few months ago. Everything is installed and working properly. However, after a few months of use, I noticed that brake fluid was leaking from the brake line connection to the banjo bolt. The banjo bolt was still well torqued to 22 foot pounds. But even a little more torque didn't stop the fluid from leaking. So I bought some new brake line washers from Dorman and installed them in place of the "A-Premium" washers that came with them. And now the flow has stopped. We bled the brake lines again and tested the brakes with more force. There are no leaks at all. You can see that the "A-Premium" discs have a reduced copper plating compared to the solid copper of the original OEM discs. Anyway everything is fine now. A small miracle, where else they could make compromises.
