I have a set of Shimano 600 (BR6203) caliper brakes I'm having difficulty with. The front is fine. The rear, however, doesn't have enough reach on the non-drive side, though it is fine on the drive side. I've tried both 700C and 27"rims with the same result. The brake shoe maybe won't ride on the tire bead, but it seems like it will. I have also tried different pads. I'm guessing it's a set-up issue, but have been unable to figure it out.
This is the best I can do. The pad hits the other side midway across the track. 39-49cm reach--seems like it should be enough. As always, Thanks in advance.
