Soon I'll have to replace rear brake pads a second time, so I had a look at this old thread... Here is a copy of my 2019 post, with updated image links...

Thank you LongRanger for the detailed process! It helped me making the job. I took some new photographs, as yours are no more available...
Step 2 and 3:

Step5:

Before step 7 : I checked the brake fluid level was not too high in the reservoir:

I used a large pair of clamps, with wooden tabs, for retracting the piston :

And checked again the brake fluid reservoir after piston retraction:

Then it's done

My rear brake tabs were really worth replacing, at about 27000 km (16700 miles):

Quote:1 - Press the piston into the caliper by pushing the caliper inwards, towards the wheel (the caliper only has one piston, on the outboard side).
2 - Loosen but do not remove the pad mounting pin (8mm head).
3 - Remove the rear caliper mounting bolt (12mm head).
4 - Remove the pad mounting pin.
5 - Rotate the caliper upwards, towards the front of the bike. If you've compressed the piston sufficiently, the pads will simply fall out.
6 - Clean up the inside of the caliper.
7 - With the caliper rotated upwards, slide in the new pads. Be sure they engage the spring on the upper surface of the caliper, and be sure the tangs on the pads hang on the front of the caliper. It's easy to see what's happening while the caliper is rotated upwards.
8 - Lower the caliper onto the rotor.
9 - Apply a tiny dab of grease to the tip of the pad mounting pin. Reinstall the pad mounting pin through the holes in the pads and the caliper. You'll need to press the pads up against the spring for the holes to line up. Don't fully tighten the pad mounting pin just yet.
10 - Install the (new) rear caliper mounting bolt. Torque to 16 lb-ft. My 1/2" drive torque wrench wouldn't fit, so I simply used an open-end 12mm wrench and did my best.
11 - Tighten the pad mounting pin. Torque to 13 lb-ft. Again, my torque wrench wouldn't fit, so I used an open-end 8mm wrench.
12- Press down on brake pedal to extend the piston and set the pads against the rotor.
