Thanks to everybody who has posted on this topic in the past; I used some of that info to change out the brake pads on my '02 VTX1800C this weekend.
Here's what I did... I bought 3 sets of pads via eBAY.
On the front, one side at a time, I:
1. Located and removed the rubber stopper that's called the brake pin cover
2. Unloosened the brake pin slightly using a "30" hex wrench
3. Removed the front bolt that holds the caliper to the frame of the wheel
4. Loosened the rear bolt that holds the caliper in place just enough to swing the caliper up and out from the rotor
5. Depressed the pistons by inserting a flat head screwdriver bween the old pads
6. Continued to remove the pad pin such that the outer pad fell out
7. Snapped it's replacement pad in
8. Pulled the pad pin out enough to drop the inner pad
9. Snapped it's replacement pad in
10. Put the pad pin back in but didn't tighten all the way
11. Spread the pads a little with a flathead screwdriver to ensure they'd clear the rotor
12. Swung the caliper back in place and rpelced the one bolt and tightened the other and then tightened the pad pin
The rear brake would have been even easier except that I didn't have a long pad pin hex bit. The pad pin is extremely recessed and I have to buy a long "30" bit for it. I'll do that later.
