The pinned castle nut that was unimaginably difficult to remove with heat and a 4 ft cheater pipe on a 12 point socket
Notice the castle nut has been dressed with a file revealing the naive pipe wrench attempts before taking more drastic measures
The interior of the emergency brake mechanisms
Disc looks great, no scars, grooves, or warpage (re-useable!)
