I attempted to change the front brake pads on my 89 GTU today and found the passenger side locking pin rusted to the caliper. I could not get it to turn even after soaking it with liquid wrench. It looks like I am going to have to cut it or drill it out and get a replacement bolt. I know it has a 14mm head but does someone know the length an threading for a replacement bolt? I am going to check the FSM. Any ideas on another way to get the bolt out of the caliper?

 

I had the same problem...b'c I did not want to disconnect the line, I had to resort to hacking It off. I wrapped a rag arount the rod and took a vice-grip to It. With a little bit of swaying, you maybe able to be as fortunate. When I Installed It back I coated the passage hole with anti-seize compound.

 

I have a strong feeling that alot of FC owners have had this problem, what size bolt does it take to replace the locking pin on the front calipers? I am hoping someone can tell me, 'cause I don't want to take the other side locking bolt off and use it to match a new bolt unless no one has had to buy a replacement locking bolt. Any help please.
