I recently built up a new frame with some new cura 4 brakes. They are excellent, great power, linear lever pull, etc. However, after racking my brain trying to figure out where a rattling noise was on my bike I have finally narrowed it down to the brakes. I can shake the pads in the calipers to reproduce the sound. When descending off the brakes it is really noisy (louder than my hub at times). When I apply brakes the noise obviously goes away. Has anyone else experienced this? If so does anyone have any fixes? I know Shimano has that issue with the finned brake pads (I never noticed that on my set)

I've had a few sets of shimanos with that problem. I just bend the spring that pushes the pads against the pistons out a bit and that solves it.
No I still haven't gotten rid of it completely. It's most pronounced blasting through chunk at high speed off the brakes. As soon as you drag the brakes a bit, you no longer hear it. I may try the teflon tape idea, or try a different retaining pin (or maybe a different pad spreading spring)
I just tried putting some antiseize On the pad backing plate. It's passed the workshop test so will try it on the trails this week
Seems to have totally solved the issue for me. Three rides in and still silence.
I wanted to share my solution: I didn't want to do antisieze as it's pretty messy, so I got a bottle of CRC disk brake quiet. I applied a small amount to the back of the pads and carefully installed them. It seems to work quite well, and might even work for shimano brake pads too.

Putting grease on the back side of brake pads sounds like a great idea
