'05 1300r brake pad replacement
In the first post on this topic Red Sonja shows how to do the rear pads...
Notice between her 5th and 6th picture she has removed the front bolt also and taken the entire caliper off. This makes it much easier to compress the piston back into the caliper, also, unlike the front caliper, these two bolts(pin/bolts, whatever they are called) are also what the caliper floats on and are enclosed with rubber boots. Don't damage the boots and be careful to get them back in place in reassembly.
Ceetro mentions in his note on that post that the front pads require front wheel removal. Even though it looks as if there is enough slack in the brake line to unbolt the caliper and slide it down and off the rotor... there is not and you will have to remount the caliper, move the bike to where you can jack it up, etc. - don't ask me how I know. Dropping the wheel is far simpler than trying to loosen and move the plastic fender out of the way.
