"How To"
Replace your Rear Brake Pads
with a note on the Front Pads at the bottom of this procedure
As with any maintenance procedure if you don't feel comfortable
performing the job on your bike,  let the pro's do it.

Out riding this morning I heard a unfamiliar sound when applying the
back brake and knew I had just hit metal.
Oop's I came home and changed them, at 33,670 miles
It would be wise to change the OEM by at least 30,000 miles
depending on your riding style this might differ.
The front pads still had plenty of pad left as shown by the Picture
at the end of this article.
Enjoy, I hope this is of some help to you,

Depending on your exhaust, you might have
to remove it to obtain access to the rear caliper.

Remove the two caliper mounting bolts
(12 mm hex head socket)

Remove the brake pad cover
(A black plastic cover)

Remove the Clips from the Pad Pins

Remove the Pad Pins

The Brake Pad Spring lifts up
(Denote that the spring has an arrow 
 designating the direction of rotation
 of the rotor upon the top, see location
of arrow 3 pictures below this one)

Remove the Brake Pads
The Caliper pistons collect dirt and this should
be cleaned off to reduce the chances of it entering
the caliper body and causing a failure of the caliper.
I used a solvent and a scotch brite pad to clean
the pistons.

Take a piece of small diameter hose place it
on the end of the bleeder screw to drain the 
brake fluid into a container.

Loosen the bleeder screw and push the pistons
back into the caliper body till all four are retracted.

Tighten the bleeder screw. 

You can clearly see the remaining two
pistons still extended

Both sets of pistons fully
retracted into the caliper body

Place new pads into the caliper body,

Re-apply the Brake Pad Spring observing the
direction of rotation arrow upon the top of the
Pad spring.
Re-apply the pad pins
Re-apply the pad clips
Re-apply the pad cover

You are now ready to install the Caliper back
on to the frame.

Check the brake fluid level in the reservoir and
fill if needed.
Re-apply the reservoir cap.
Place your hose on the bleeder screw and into a
container to retain spilled fluid.
Pump your brake pedal several times and hold 
the pedal. 
While holding pressure on brake pedal, loosen
bleeder screw, fluid and excess air will expel
from bleeder screw hose into container, 
hold pedal fully forward and tighten bleeder screw.
Pump brake pedal again and repeat process till
all the air is expelled from the brake lines and
the pedal is firm and not spongy.
Refill Fluid Reservoir and check operation
of rear brake.

The Picture to the right is a set of front pads
with 33,670 miles on them, they have plenty
of pad left as you can see by the depth grooves.
Both calipers looked the same.
