    Disc break in

    I'm running stock shimano disc's on my 09 Kona Cinder cone. I'm having the hardest time centering the rotor in in the caliper. And even when i do get it to where it's someone centered, after an hour so of riding it starts making noise like the rotors bent (but it isn't).

    anyone have a similar problem and what was your fix. My next guess is that the pads are unevenly worn?

    Check the bearings in the hub. loose/worn bearings will give these symptoms as well.

    Make sure the axle/quick release is very tight.

    If the pads are well used, get new pads.

    It's common for new brakes to squeal and or groan. It should deminish as the pads and rotors wear into eachother. It could take several long rides...
