It is possible to remove the rear caliper and replace or de-glaze the rear pads without removing the exhaust. Most manuals I've seen show how easy it is to do with the muffler removed - but apparently you are not supposed to re-use the exhaust gasket, so I want to keep the exhaust bolted up.
CALIPER OFF - Muffler Still In Place!
STEP
1) Remove the 8mm bolt of brake hose holder to give yourself slack in the hose.
Push the caliper body inward to push in the pistons.
2) Use a steel 5mm "L" shaped socket head wrench to
just loosen these 2 pad retaining pins.
A socket will not fit behind the muffler. Loosen them both before you remove the caliper.
3) From under the scoot loosen the two 12mm caliper bolts. You will NOT be able to remove them all the way - muffler is too close. No worries - thread them out as far as possible and the caliper will come off.
4) Tilt the caliper top towards you and slide up and over the disc, remove to a clean work surface next to the back wheel.
5) Unscrew the pad pins and remove the pads.
6) Sand/clean or replace your pads.
7) Apply silicone grease to the caliper bracket slide-pins. Install the caliper bracket to the caliper.
8 ) Install the pads into the caliper. Insert both pad retaining pins and start by hand but don't tighten them until the caliper is mounted.
9) Install the brake caliper so that the brake disc fits between the pads.
10) Install the two brake caliper mounting bolts with a drop of Blue Loctite and tighten them to specification.
11) Now tighten the two 5mm pad retaining pins
12) Remount and snug the 8mm the brake line holder bolt.
13) Look things over, take scoot for a walk and check the rear braking before starting engine. Ride slowly until new/clean pads are seated.
So, renewing the rear brake without removing the muffler/exhaust IS possible!
