I own a 22 Lexus IS 500. Rebuilding the calipers after getting them powder coated. While putting them together I’m missing this metal dust boot retaining ring. I cannot find this anywhere and the caliper rebuild kit didn’t have this part with it. I need help. It’s for the front calipers they are 4 piston advics brakes that came on my Lexus. Any schematics I find for this either don’t show this ring or don’t show the correct brakes I have. In the picture you can see it missing on the left side. And the last picture shows the whole brake if you buy it online as a reference for what it looks like. Please help. The inner diameter of that ring is 43mm if that helps
