No gasket for brake caliper rear of VAG?

I broke up two brake calipers and tried to reseal them.
No problem for brake pistons, but the seals for the steering lever of the hand brake are not available at VAG? Can this really be true that one should buy a new caliper because of an O-ring and a small seal? What is this...................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

I feel better now. Where the hell do I get the gaskets?
