I rebuilt an old Peugeot and swapped out the old steel rims for new alloy rims. I then cleaned the existing caliper brakes and put on new brake pads and cables, but they just don’t stop the bike. So I bought new Shimano brake pads designed for AL rims + caliper brakes, but same issue - no stopping power! The rims keep going even with full braking pressure applied?
Any ideas?
