there, I just got a new motobecane bike off of bikesdirect and it comes with this disc brake
SHIMANO DISC-BRAKE SET ULTEGRA, ST-R8000, BR-R8000 FOR 25MM MNT, RESIN PAD SHIMANO KSMMAR160DDA MOUNT FOR ROAD DISC BRAKE MOUNT SHIMANO ROTOR FOR DISC-BRAKE, SM-RT76, 160MM, 6-BOLT TYPE
I put the bike together and when I spin the wheels, the brake pads are certainly rubbing constantly the rotor.
and here's a link to a video I made about the problem.
I have tried squeezing the brake while re-tightening the bosses on the caliper (at least that's what I think it's called), the thing that's actually attached to the bike frame.
I notice also that there is a piece of metal between the brake pads, it's very thin and is folded like a butterfly, should this piece of metal be removed?
What else would you try to fix this?
