HELP!!!

So got my calipers powder coated by a local shop(will start another thread about them later) and today while re assembling the calipers, I felt a grind when replacing the bolts that hold the caliper halfs together. So I instantly reversed the ratchet to pull the bolt out to see what was going on, and it locked the bolt. Now it won't turn any way I try to turn it. I checked the other calipers(the unassembeld ones) and found that there is dust trapped where the bolt threads into. My question is how do I loosen the bolt that is seized, also is there a way I can clean the threads for the calipers myself?

Use a tap to clean the threads, if it gets tight back up a little and go again.

Please elaborate on what a tap is?

Taps are thread tools that cleans threads as you tighten the tool.

ok but how do I get the bolt that is stuck out?

Use some WD-40 on the threads, And let it sit a bit.

Got the bolt out. Thanks trips. Heading to sears this afternoon for a thread tap

Be careful with the tap! Don't force it, let it do the work. Like I said before if it gets tight back it up and go again.

Ended up speaking to the shop the powder coated the calipers, they said to bring it by and that they'd take care of them as it was their mistake. So I'm going that route instead of risking the damage to the calipers seeing as I'd have to tap every thread if I went with that option.

they should just have to use compressed air to clean the junk out. Don't know what method they used to strip them though. If it was chemical, it might be a little more involved.

I tried compressed air but it seems to be stuck in there. He said It might be sand from the bead blast

Soo I went to the shop this morning and they got all the dust out but when I asked for some bolts that I was missing(see pictures) he told me that he didnt have them but that he thinks they were just plugs.

Now Im about ready to redesign this guys face, so can anyone tell me What goes in those threads? Im really trying to avoid going back there.

Also when I got the bolt out it, it was stripped at the end. Should I still get that tap and go at the bolt and thread with it?

Just tell us CA guys where you went so we can avoid this place. How they screwed this up is inexplicable.

Apmd powder coating in Ontario.

Can anyone answer me?

Yes there are supposed to be bolts in those holes.
