Rear Caliper Masking

Before masking off the joining surfaces of the 2 halves I decided to check out the pistons to make sure they were still ok . . .and sure enough with aid of an old brake line and a bicycle pump the pistons popped out and they are great, no rust or marks on the surfaces and the internals of the caliper are like new, great I can now go ahead and recover the caliper in the original bright red finish.
