DA 7402 caliper adjustment

[bikenut2010]

replacing 105 with DA 7402 calipers on retro build....advice needed, one arm reluctant to spring back leaving the caliper askew; I don't know how to centre the caliper ( side pull ) and have the pads return to the original position after releasing the lever; new inner cable fitted so I don't think it's binding.
There are no plastic spring carriers in the lug in the casting... clues please! :?

If it's just a case of the caliper not centering itself after use, remove the black rubber bung at the front of the caliper, insert the correct allen key and turn gently. The whole caliper will rotate on its mounting axis and it should now stay there after use. If not, tighten the mounting bolt from the rear then try again.

7402s are the easiest side-pulls I've owned for centering and staying centered. Love 'em
