Doing my first pad change on a 512 tr and have a few questions: 1) I believe you have to remove the locking pins on the front calipers with a small diameter center punch, but the manual talks about pin locks. I can't see where these are installed, and how are they removed? 2) The spring lock on the rear calipers is retained by a locking bar. How is the the spring released? It seems that one pries it off that bar but since there are no marks indicating this has been done before, I believe I am wrong here. BTW did a search of the archives but to the extent its covered, these questions are not answered AFAIK Can anyone help?
Problems solved - 10 Locks reveal themselves when pins are punched out; 2) squeeze spring in the center vertical plane and the spring shortens to disengage the upper retaining bar. QED.
