I misunderstood the poster's question. When I meant to communicate is that when I spin my wheel backwards--as if moving in reverse--the rear wheel stops more quickly than when moving forward. The brake pads, though new, were developed for old steel rims. They have a leather strip in the middle that helps with braking. It's certainly not the pads. The front pads stop the front wheel. How can I tell if there's an issue with my rear brake cable?
