Procedure to replace the seals
 

I found this procedure for replacing the seals on the twin spot calipers. Great way to see whats required, but I'm not having any luck finding seals either. My pistons look fine, the dust seal is a little ragged, and I would like to just find the dust seal?

Thats a good article on piston removal. My method was a little different, since they were getting powder coated. I didn't remove the pistons until the caliper was split in two halves. Then I just plugged all holes, but one for air. Next I wrapped a shop rag around the half (to catch pistons), and eased the air pressure on until they popped. This can get dangerous fast :eek: , if not done carefully.

Especially when you are looking over top of the caliper to see why they haven't come out of hte bore yet!:p
