hi all,

My front HFX-9 with an 8" rotor emits a "beeeeee" sound everytime I pull the lever - most disconcerting going down a long 10% gradient hill along my commute route. I presume this isn't normal as the rear with a 6" rotor does not do this.
Does anyone have an idea what is causing this? Loose brake pads? The brakepads feels a bit wobbly although that's totally subjective. Or could it be due to a poor bleed? Any help would be much appreciated.

I've worked on a few bikes where the rotor dragged on the caliper adapter when the brakes were applied. It made kind of a "buzzing" sound. If this is the case, the fix would be some minimal file work on the adapter.

Hi Speedbump,

thanks for the suggestion. I'll check for the dragging, although the rotor doesn't seem to be touching anything it shouldn't when it's applied - that's with the bike at a stand still though.
I've also bled the brakes since my shout for help but haven't had a chance to go out for a ride yet. I'll mind to take a file with my next ride. Thanks again.

Mine do that a lot. I think its just the edges of the openings in the rotor coming in contact with the edge of the pad. Kinda like a baseball card in the spokes. I wouldn't worry about it.
