I tied liquid wrench for 1 hour about 15 repeat then hit with an impact wrench no go. Then I tried heating it up with the torque and hit it with impact wrench, still no go. I took a look at it closer, look like not just the screw thread got siege but the pin also appear to have been stuck as well. The cause might have been because overheating causing it to melt and self soldered. In the head I purchase a new complete set of caliper for $60 on ebay, who cares it’s china made, just have to review test it properly before installing and test it again 🙂 and it will not last long so keep that in mind.
