As far as I can remember it is the part that is threaded not the caliper.
My bolts would not come out. I ended up cutting my caliper in half to get to the rear of the bolt. Mine required heat, penetrating fluid, drilling the bolt from the the rear to about 6.5mm diameter and still I broke one socket extractor before finally getting it out with the second.
You need to check the bolt as to which thread it has - earlier are coarse and later fine. Make sure you know which thread you have before clearing your threads with a tap/thread chaser.
This is the rear of the bolt drilled 6.5mm as I thought it may reduce the strength of the bolt and allow it to turn. It still needed heat and penetrating fluid.
This is the difference between the threads on older axles compared to the fine threaded bolts on the later axle. I think the change came around the 200tdi to 300tdi but can't tell you 100%
