To change the rear tire requires the following several steps including, removal of disc brake pads and compressing the brake caliper piston inward, removing the axle and drive belt also required . After completion of the Disassembly and then reassembly of components including brake pads.The rear brake master cylinder failed, to function, no hydraulic pressure was supplied to activate the brake caliper. I believe when compressing the caliper piston inward (which is a common and necessary practice) caused the master cylinder to fail. Researching this issue I found that this is a common failure to 2004 - 2006 Harley Sportster motorcycles.

Reading this record
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
