I'm interested in putting a discs brake on the right side of a bicycle. The goal is to have dual front discs, similar to how motorcycles often use double front brake discs.
I can buy or make a custom hub with two discs. That won't be a problem. And I can arrange a second brake tab on the fork, or even make a custom fork altogether. The problem in question is that disc brakes are engineered to fit on the left side of the bike only. Mounting one on the right side would be straightforward, but the braking forces would be reversed compared to the normal mounting. It would be like braking while the bike was rolling backwards. Would this cause any problem? Are the brake pads designed to take brake forces in either direction equally?
Back in the days of u-brakes and v-brakes, we saw them mounted both ways by being mounted sometimes to the top or bottom of the frame stays. So we know those worked either way. But I have not seen the same variation for disc brakes.
