Campagnolo brake, closes unsymmetrically The rear brake of my road bike closes unsymmetrically which results in bad braking performance and the rear wheel is getting pushed to the side. The Video describes the problem best.

The arms of the brake move and close symmetrically if I uninstall the brake an push the arms with my hand together.
In the very last image of the video there appears to be a small screw hole in the caliper. Looking from the right side of the bike it is behind the exposed cable, between the adjuster and the cable clamp. That screw will adjust the spring tension. Turning the screw "in" will increase the tension on the spring. The increased tension will delay the brake movement relative to the other side. Based on your video I would think you need to back the screw out. Start with 1/4 turns. As others have commented if you can't adjust the issue away it may be time to strip them down and clean and lubricate the pivot points.
