Now that I've also been caught, swapping original discs and coverings for textor discs and Lucas coverings, I've also got caught, I drive an ICE, as far as the brake noise is concerned.
1000 km everything was OK, then the drama came.
Saddles and brakes are on my thickness OK, this only in advance, I have made everything clean, adhesive rests of the outer lining back are naturally removed from the saddle, as well as the foils of the adhesive foil outer coverings, so everything as prescribed.
Since I'm annoyed with squeaking, I've got an Ing's phone number through an indiscretion. the brake lining supplier group for Audi, discs are supplied for the A8 from Brembo, whereby the Audi original discs are turned off again.
Rubbers are delivered by JURID/PAGID, even if Lucas is on it, because Lucas is the brake system supplier.
Jurid drives in production only one quality, original like After Sale Market, Pagid has 3 qualities, Premium is like Original.
Lucas and ATE pads are manufactured in Italy and Spain because the brake manufacturers Lucas and ATE do not have their own production and only buy, usually. lower quality.
It is known that the double piston brake installed in the A8 is vulnerable and has been employed since the brake is no longer used, although it has fantastic values.
According to the Ing., who led the driving tests after various customer complaints, the saddles of the Lucas brake are extremely susceptible to vibrations in the low frequency range, therefore the coverings and discs are of great importance.
For this reason, I will now throw out the Lucas coverings, assemble original coverings, and complain about Lucas, because a question in Ingolstadt confirmed the first statement, albeit under the hand and unofficially.
This is only a possible solution, whether it is the panacea, provided the saddles are OK, the future will show.
