Got the pistons out of the calipers by pumping them out, easy peasy. Thanks to Ed (Phoenix) for enccouraging us to do it that way. Would have been a mess otherwise. The SS piston came out covered in corrosion from the rusty pad. The phenolis one came out relatively clean.
I've got one of each as I broke a phenolic years ago. I've since scored anther SS and it will go back together with 2 SS, just for the symetry.
Spent balance of time cleaning the calipers, ready to reassemble.
Blisterpack for these pads has a copyright of 1984 on it.
Spent some time modding the combo muffler mount/centerstand stop. I hope Saldanas can take it as a template and make one from billet, or weld it up anyway.
