Hi all, just after a bit of advice as a newbie returning back to cycling after a 25 year sabatical I have recently bought a Gt Timberline 1.0 for my short commute to work and after approx. 1 month of riding I have noticed that the brakes bind a little f &r so I thought I would take a look, It would seem that when I squeeze the brake levers the pads push the disc over to the other side of the caliper / pads causing the disc to distort slightly and is this isn't what I expected I thought I would seek some advice, any help would be greatly appreciated, thanks.
