undo 1 lug bolt on the loosest wheel - might need to lower the car or increase the parking brake clicks if you don't have an impact wrench

undo parking brake to rotate the open lug hole to access the parking brake adjuster through the hub

re-click the brake to the original 3 click amount

adjust the clamping force so that the wheels now require the same drag to rotate; if you have no "feel" to accomplish this process accurately, then you may want to quantitatively do this by figuring out how much torque the tighter wheel takes to break free/rotate with your torque wrench, then match that torque to the loosest wheel.

replace missing lug bolt and torque

done!
