Great patience is required,,if you do not split caliper, these are spring pins,, the design is from an engineer who in a last desparate effort to warn the world(not sure of what) installed these in the fiero just before his move to ford.. I made my own tool from I think a 1/4 rod I hate these pins I drove one out but using a punch to drive them out damages the pin and the replacements are not cheap..you have to make a small slide hammer or a devise that pulls the pin out thru a sleeve .you can find the parts you need to build the tools at a hardware store
try to drive pin out a slight amount before using tool.lube pin before removalm,squeeze one end firmly with channel lock(made me feel better ha ha follow jazzmans advise
I was going to design a c clamp with a hole drilled in it to remove these but got them out after my lady friend performed druid ritual to remove sin
chilton manual has drawing of factory tool,just a small slide hammer,you must back up the nut with many others( you will see)
others will have better ideas,, my pins were tighter than I am with a nickle
