Need some help on disc brake setup-Posted in MTB but getting no response, should have posted here first anyway....


I'm helping a buddy put his BD Motobecane together. Overall, the quality looks good and the thing has gone together really easy. Wheels were true out of the box, small tweaks to derailleurs including raising the front der slightly. Blah blah blah.....


It's my first time setting up disc brakes. This one has mechanical Tektro's (low end, likely the cheapest ones they make). They really grab nicely, stopping power is good and it has me thinking of making the switch. However, when I turn the bike or lean in either direction I can hear the front disc rub. It's not enough to create any real friction, but annoying. Is this typical? Someone please give me some education. I've spent a lot of time adjusting the pad clearance on both sides of the rotor and even tried to "true" the rotor.

Thanks!
