I have some spare Textar pads and they some shim installed on the piston mating surface.
Replace with sebro and they still squeal (brembo sport pads)

I also had a bad experience with D911 brembo discs (shaking when hot), replaced with Sebro and they still squeal (Brembo sport pads).

I use copper grease on my daily cars but for the Porsche I use something like Mintex CeraTec, Bream B-Quiet or LiquiMoly Bremsen-Antu-Quietsch-Paste.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So I bought a brand new brembo discs and pads kit for my c4s from Design911. Fitted them all myself with no issues, it was surprisingly easy.
However I now have squealing brakes at low speed. Done some research the only thing I did not do is put copper grease or equivalent at the back of the pads. The youtube video I watched did not mention it unfort.
Would it solve my issue? Would it be fine to remove them to add the grease? What grease shall I use?
Some new pads have an anti squeal coating on the back but I tend to be a bit old skooll and put some grease on the back just in case. I use copper grease on my daily cars but for the Porsche I use something like Mintex CeraTec, Bream B-Quiet or LiquiMoly Bremsen-Antu-Quietsch-Paste.
Did you put the stick on anti vibration damper pads on, that fit into the back of the pistons? I think they are also some sort of antisqueel too, but make it more of a PITA to remove the pads frequently.
It should be fine to remove the pads and slide back in (in you haven't stuck the damper things on).
I have stuck the anti squeal pads (the ones which goes into the back of the pistons) so that is not the issue, obviously it does mean that I will be tricky to remove them to put the copper grease now...
I never understand how squealing brakes is caused from the back of the pads, I mean you might get a very short squeal once when you brake but for it to continue it must be the pad material on the discs...right??
I bought some Brembo discs for my Turbo like you from D911 and they warped , totally ruined a trackday in Anglesey last year. I bedded them in really carefully for 1k miles before going but they warped whilst on track and braking was horrible so I quit the track. D911 eventually took them back and I got a refund.
I wasn't bashing the Turbo , I just wanted to be on a track so I could explore what the car was like in the safety of a track, also I have very little track experience , it was great fun until the discs warped.
In my experience the brembo pads just squeal.
I also had a bad experience with D911 brembo discs (shaking when hot), replaced with Sebro and they still squeal (Brembo sport pads).
I recently switched to Sebro (slotted) and Ferrodo DS2500 pads, only occasional squeal. Prior to that I had the stock drilled with racier Pagid pads which were a bit of a pain for squealing.
Porkchops, is this only at low speed when coming to a stop? If so, I've got the same problem. I'd try bedding them in (5 firm stops from 50mph to walking speed, allow to cool then repeat but from 60+mph). Hopefully that fixes it for you. I think my pads need de-glazing. Either that or its the rears which came with the car. Sebro slotted disks are on my list too but its not worth doing it at the moment.
yeah it's only at slow speed when coming to a stop...really annoying, I have been trying to bed them in but with no success. I will try your technique again...Are sebro slotted disk better?
I too have the annoying squeal at slow speeds, having bought all genuine parts, I did not expect it.
I have read that unglazing the pads will stop it, but not convinced this will resolve the issue.
Perhaps you were unlucky & had a bad batch?
I bought the D911 kit of Brembo discs & pads a few years back & had them fitted by Precision Porsche. I think they used OEM vibration dampers rather than the ones supplied by D911. I'm not sure what grease they used, but I had no issues with squealing & performance was great. However they did generate more brake dust than the OEM pads.
my brakes squeal at very low speeds. I have Textar pads but not 100% sure on the discs. My last car, I installed Brembo discs and pads, and I never heard a peep from the brakes. I have some spare Textar pads and they some shim installed on the piston mating surface.
