I’m not a Ford guy but on GMs you can take the whole works (caliper and bracket) off, two bolts. Then put in a vise and work on the pins. I have heard some of the Ford caliper pins/bolts tend to corrode a lot; might be a good idea to pick up couple of new ones and boots (might come as kit) before you rip into it.
Yes, there are two large bolts holding on the entire assy., but those are pretty well locked up too. Granted, I’ve not put nearly as much effort into them, yet. Might have to.
Agreed, if the corrosion you mention is significant, my costs are going to run up, too... Am going to look for boots anyway, as while these look pretty good, they may not be after I try heat (assuming I’ll have to).
