I do happen to have a brand new set of mk3 calipers in my shed, they need new seals. And i do have a seal kit.
I bought calipers a year a go,had problems , and ended up havin another pair sent. They were sh!t too, so i replaced the seals and all was ok.
So i got a spare set with new seals to put in.
If anyone is local then i might consider selling them but i can't really be bothered to start posting them.
