416B Parking Brake Diagram And Adjustment

Does anyone have a clear pic or diagram of the parking brake caliper on a 416B ? The diagram listed in the factory service manual I have is of extremely poor quality. I have seen numerous threads referencing a 3/4” nut and jam nut in the Center of the caliper , but on the 416B it appears to be a different arrangement.
Without proper diagram the service manual seems like complete jibberish ! Any help would be greatly appreciated! Thank you in Advance !
