BMW K75 S | How To Replace the Rear Master Cylinder

During the shakedown ride, the rear brakes didn't seem like they were working very well, so I tried to bleed the brakes but couldn't get any fluid to come out. Then I pulled the master cylinder and it didn't seem like the fluid was getting out. Tried to pull the piston out to rebuild the master cylinder, but it was seized in the bore so decided to just buy a new master cylinder. I also ordered new stainless steel braided brake lines from Spiegler and replaced those - both front and rear.
