I remember seeing somewhere on here and after searching and not finding it, Im hoping someone can point me in the right direction. I am in the process of rebuilding my distribution block (brass block where all the brake lines connect to) and remember someone had a kit to rebuild it with. There was the two o-rings for the pistons and one larger o-ring for the sensor. I can not use my original ones as they seemed to have swelled as I had a heck of a time getting the pistions out of the bore.

Thanks in advance.
