I have a master cylinder kit which I got from AJ and it was cheap too..
( master cylinder is the same as a Jenson Intercepter )
The master cylinder only has Two seals which do any thing.
One is a quad ring which is nothing special and a normal type piston seal.
My master cylinder already has a stainless seleeve in it.
I will see if I can up grade the quad ring to a Viton one.
