Some brakes just work, others don’t. I bellive this is a great deal to do with set up on the bike and if you have decent tight hubs.
Get the mountings properly faced so the caliper runs perpendicular to the disc.
If your hubs have a lot of lateral play, you will get the jangling sounds as you corner. It will be more noticeable the bigger the rotor you have fitted. Check your wheel bearings and make sure the pads aren’t too badly worn. I used to have closed brakes where you can wind the pads in and out so that they run close to the disc. This seemed to minimise the problem.
After 9 years of faffing, i’m not convinced there is anything you can do to completely eliminate problems. Just hope you get lucky and everthing works most of the time.
I have tried numerous Hope brakes and a set of Hayes Stroker’s. They all played up at various stages. I have just learned to live with the hassles.
