This is a long shot…
I am missing one bolt to attach a Suntour Roller Cam Brake
Pictured below are two bolts. The bottom one is correct.
The shank needs to be 6mm long. The top bolt shank is .5mm too short, which causes it to pinch the brake arm in place.
I may try to file the shoulder of the wrong bolt down .5mm.
Open to any suggestions.
