XJ750J Caliper DISassembly questions

So I'm taking apart my (donor/test/experiment-on) calipers that I want to rebuild and paint. [If bore is usable, I'll rebuild this set. If not I'll rebuild my running bike's calipers].

I got the brake pad retaining pins out with difficulty (Kroil just ordered, so I used PBblaster).

Now I'm trying to remove the pins/bolt that hold the mounting bracket to the main caliper body. These bolts have been assembled for over 30 years and are quite stuck.

I don't have a large enough vice and accessing those pins/bolts on the bike is not possible.

Other than finding a larger vice, longer 14mm wrench and some Kroil how can I get these pins/bolts out? Should I even try? What is keeping the non-threaded ends in the caliper body?

In the picture below I'm trying to remove the yellow/orange/red parts. Red is the threads. Orange is the hex nut area. Blue are replaceable rubber boots. Green is the pad pin I managed to remove.

P.S. I have the factory service manual. That is where the picture is from.

 

Fitz will know

 

Any other suggestions besides more leverage and Kroil?

 

The pins "slide" into/out of the caliper body. Shoot the Kroil down into that area. If the pins get cocked it can be a bear to remove the bracket from the caliper body....it has to come pretty much "perfectly" straight out. An minor airlock can also form. I would NOT try to dis-assemble the slider pins from the mounting bracket....they are on there TIGHT and we've never been able (or, really, needed to) remove the pins.

 

Thanks for the info. I'll try that when I get a chance!
