Both front callipers have bent the outside brake pad. It’s clearly down to me not replacing everything correctly but I’ve srtipped and rebuilt these brakes a hundred times. I put it down to the change of rubbers (and pins) I did before last summer. The better fit of the new rubbers stops the carrier from retracting properly. Not a problem once the whole thing’s together and on the bike, but an obstacle to getting the thing on properly in the first place.
