I Just got Fly Bikes manual brakes today that I ordered from danscomp. There are rubber insert type things in the calibers where the mount goes in. Because of this, the mount does not fit. Should I take the rubber out? And the bolt that tightens the springs is no where close to long enough to reaching the frame. How do I install these??? I have the Fit Van Homan Signature. I need my brakes back!! Please help if you can! Thank you.
