My 4s came with a C-spanner in the tool kit but you don't need it for the rear preload. The adjustment is all done with the hydraulics what's more the lockrings have a pin fitted to lock their postion. You would need to remove that first to adjust them. It's my reckoning that the lockrings are not intended to be adjusted by the user.
