Squeaky clacking brake pads
They're driving me nuts. Can I add shims or grease the part of the pad where it meets the piston?

You can buy the blue goo that goes on the back of the pad. I've also used several strips of duct tape on the back of the pad as a dampener.

Does this blue goo have a brand name?

I heard bad things about that blue goo.
Pelican Technical Article: 911 Brake Pad Replacement
11. Do not use the anti-squeal compound pad from your Friendly Local Auto Parts Store on the back of the brake pads. This stuff turns to glue, and when you need to replace the brake pads again, it will destroy the caliper dust boot when you pull the pads out (don’t ask how I know this). Many new brake pads come with an anti-squeal coating already applied. It looks like a thicker coat of paint on the back of the pads. If you want to use something more I recommend a LIGHT coat of Lubro-Moly Hi-Tack Lube Spray. Be careful not to get this stuff on the braking surface of the pads, or on the rotors.

I did my brakes last summer. As I was painting the calipers, everything was thoroughly cleaned. I bought the Porsche (Brembo) pads for the front, Textars for the rear, and Zimmerman coated non-drilled rotors. I also used the anti-squeal pads that Pelican sells and chamfered the leading edges of the pads.
No squeal, squeak, chatter... nothing. They are completely silent.
Perhaps if you removed the pads, cleaned everything, and installed the same anti-squeal pads, it would solve the problem. Be worth a shot anyway.

What I like to use is WURTH CU1100, its a high adhesive lubricant that I use on all breaks. Its an anti-corrosion copper paste.

I use CRC disk brake quiet. Cheap and easy to find. Never had a squeal. I wear out/change my brake pads 3 times a year due to heavy track duty. Yes, it gets cooked from the high track temps but never resulted in a problem.

I use the CDC in spray form with good success. No one has mentioned the dog ears on the ends of the pad. Be sure the channel they travel in is clean and smooth.
Also, I tend to not wash my cars as much during an extended dry spells - they stay clean so I don't need to. The down side is brake dust can accumulate and cause squeaking. Part of your issue may be dust build-up. Shoot those rotors well when you wash.

Tried some CRC on the front pads. Never really dried, but stopped the squealing. Took it for a spin and I have squeal From the back too. Grrrr.
I chamfered the pads too. That should help. And, the CRC stuff stopped the clacking when I back up after the pads and discs are hot.
Tonight I'll jack up the back of the car and do the rear pads too and hopefully, that will solve the problem until next pad change.

When I replaced mine, I had a squeal start several weeks after the brake job. Order from Pelican, Wurth Anti Squeal Spray, 300 ml...NO more squeal.
