Hi mate welcome back glad to hear you kept the Scoob :) as for the calipers mate I had a problem with mine and got another set like you I was going to refurbish them too but decided I didn't have the time to do it not even at a slow pace :(
But I'm sure you have to get them out with a grease gun or something that gives loads of pressure
I came across this pretty good vid, I know it's not subaru calipers but basic idea :D
