s12 rear brake spanner
 

i was changing the rear pads today and had to twist the pistons back in, when i thought, what can i use, then all of a sudden i thought, will the tool for changing the handle grinding discs fit:D , it sure did and perfect it was, although the calipers where only a year old and i could of turned them with my own fingers:rolleyes:

iv done the same in the past but you can only get a quarter turn at a time so i got mi welder out and made a tool :cool:
