Front brake pad rattle (non OEM) after replacement

[B8_Jim]

I've tried searching, and didn't have any luck finding the answer - so sorry if this is a repeat.

Replaced the front pads a few months ago - didn't have any issues - greased everything and I have no squeal, and they perform fine.

However - when hitting a sharp bump - I hear a metal on metal "clack" from the front wheels. Going over really broken pavement or bad RR track crossings there is a rattle. If however, I have my foot on the brake - even ever so slightly, there is no sound, so I assumed it was the pads.

Took things apart today, and it's pretty obvious the pads are moving around in the caliper enough so that the U shaped slot in the pad backing plate is contacting the pins on the caliper bracket. Paint on the pad is gone/and a shiny metal area exists. Similar area on the pins that shows wear - see below.




I know the OEM pads have an adhesive backing that glues the outer one to the caliper, and the inner to the piston. The clip that holds the inner pad in the piston is pretty tight - thinking the pad may be rotating more than both sides moving, but...

How can I prevent aftermarket pads from making this noise? I can't find anything similar to the OEM pad glue. I know it's probably just a nuisance, but it makes the car sound like a beat up junker when I hit sharp bumps.

Thanks,

Jim

Exact same issue here. Clank happens even with lane dots. Curious if there is someone that has a solution as I haven't been able to resolve it.

Same problem with my Akebono Euro pads.

I took the brakes apart and greased everything with brake lube but the problem persists.

I have same setup on my wifes B8.5 A4 and there is no issues.

The backing plate of the outer pad MUST be glued to the caliper to prevent the rattle. That's how the original factory pads were installed.
Clean the back of the plate, and the inside mating surface of the caliper with solvent (like Brake-Kleen) to remove any grease/dirt, then use a little bit of CRC Disc Brake Quiet (red adhesive, in a small bottle) to glue the pad to the caliper, then re-assemble.

The black paint coming off the "ears" of the backing plates, where the plates contact the caliper-reaction-bracket is normal.

So I pulled the fronts, cleaned thoroughly & applied CRC Disc Brake Quiet and re-greased the contact ears. Akebono's are still slapping around like a pinball over every road dot. Annoying as hell! Suggestions?

I will be replacing the akebono pads under warranty.

My wifes car (b8.5 A4) has same brake setup with no issues. I did not glue the pads or did anything special.

Lubed the back and the guides and good to go.

The pads have raised circle part on the outer pad to keep the pads secured in the caliper. I don't use adhesive on the outer pad and never made rattling noise. FYI I've used stoptech, hawk, and now Jurid (OE Manufacturer).

So I CRC Brake Quit-ed the pads and the problem is improved, but not solved. I can now hear a squeak which sounds very much like the inner pad tabs moving around inside the piston, and still have the rattle. I bent the tabs/springs on the brake pads so that it fit into the piston very tight.

What else can be done?

Is there an actual adhesive pad similar to what the OEM pads use that can be used on aftermarket pads?
