Need help badly with brake pad change, i have run into a problem (pic)
The top shock part that should go in and out with pressure is siezed, need ideas to get it moving again. I have taken the bolt out and swung part of the caliper down and it will not compress enough to get the caliper back up.

You dont need new calipers. Those can be removed eventually and be replaced with new sliding pins.
In fact, most of the time they're stuck because the grease inside became hard. When I had that problem, I somehow pulled it out, cleaned it, regreased it, and it worked like new afterwards.
You may need new calipers if the sliding pin snaps inside while you're trying to pull it out. Obviously you wouldn't be able to get it out in short of drilling it, but that's a different story.
Spray some PB Blaster inside the rubber boot and let it sit. Then try to use a rubber mallet and smack it around a bit. If all goes to plan, the pin should break free and you'll be able to pull the pin out.

pull the boot back and use wd40 with the straw and stick it in there and spray the crap out of it 3 or 4 times and lighty tap it and pull it should free its self. after you free it up use brake grease to pack the boot up and also do no forget to use the grease on brake shims or your going to have squeaking while braking i put it on the piston and between the shim and brake pad good luck

I sprayed in Wd-40 in at the time, but PB Blaster works better.
I used a rubber mallet and hit the sliding bolt a few times to give it a 'shock.' You may or may not have to hit it hard. I used this method first so the caliper pin can slide. Then I used a 17mm socket to break any debris inside. Eventually I got it out.
Keep the caliper (w/pistons) on the car, but remove the caliper bracket from the knuckle. Lay the bracket on the floor and hit the sliding bolt with the mallet.

I would remove the bracket from the hub and do what GSteg advises.
try to resist using your 17mm, too much force can shear the head right off that pin.
Propane torch works well as last resort.
A new bracket is about $110 at the dealer.
Good luck...

Well I manage to bang away with a non-rubber hammer and mess up the threads inside the sliding bolt thingy, I'm just going to put the old pads on till I have a chance to work on this more. Can I just tap the hole for new threads?
