Thruxton Fitting 1200 Rear Pads

On the Thrux 1200/1200R, do I need to remove the rear wheel to remove the caliper and fit the rear pads? I cannot see the usual caliper mount bolts, just the torque arm mount bracket with caliper attached some how. Web searching does not come up with much for the 1200.

Just noticed my rear ABS ring has got scraped around the outer edge so assume its the edge of the pad backing now making contact. Even though there appears to be about 2mm of meat on them. Bit of a sod because the ABS ring is not cheap looking at Fowlers prices.
