Adjusting brake pads When I use the adjustment screw to adjust how far the pads are away from the rim,
neither side moves the pad.
Is there a fix?
The brake pads on this kind of brake (V-brake) are adjusted with the screw above the one you've circled. The screw at the end of the pad adjust the positioning of the pad relative to the rim. It's one of the jobs where you ideally need 4 to 6 hands to get it right.
The screw that you circled adjusts the symmetry of the pull, or the timing of the pads touching the rim by adjusting the tension of the springs in the pivots.
