Somehow my pad spring twisted itself into the pads/rotors this morning and made a horrible noise. After much faffing, I replaced the pads and spring but the tiny little split ring that holds the pad retainer bolt was wrecked and pinged off into somewhere unknown.
Do I need this bit? Anywhere I can get one? Seems like it's just a "back up" safety measure but I guess it's better to be safe.
And I simply cannot find anywhere that sells them! Any ideas?!
