Trying to install avid shorty ultimates. The left (pictured) arm engages. But the right pulls towards the wheel already with tension on the saddle arm. So when I squeeze the brakes the left is the only one that moves. The right arm is already touching the rim

you need to set the spring tension on both arms to be balanced. loosen the allen bolt in the middle, turn the red square thing towards the outside with a box wrench (i think its a 15) and while holding it in place, tighten the center bolt again to lock the adjustment down.

Looses the bolt and use a cone wrench to adjust the red square piece. Clockwise for more reaction, counter for less.

**TENSION THE BRAKE**
19. Use a 15 mm fl at wrench to turn the spring cap so that the hole in the cap is at the 3 o’clock position for left brakes (L), and the 9 o’clock position for right brakes (R), Torque the brake bolt to 5-7 N∙m (44-61 in-lb).
To center the brakes or adjust the brake tension, unthread the appropriate brake arm brake bolt, use a 15 mm flat wrench to increase or decrease the spring tension, and re-torque the brake bolt to 5-7 N∙m (44-61 in-lb).
Increase the spring tension on the arm that needs to move away from the rim. Loosen the fixing bolt and turn the red square part to increase the tension, then hold the adjustment while tightening the fixing bolt

Most cantilever brakes have a screw in one or both arms to adjust spring tension according to need.
Use that screw to reduce the tension in the left arm, or to increase the tension in the right arm, since the right arm moves towards the wheel more easily than the left arm.
