so on newer bikes with big rotors and radial calipers, is there an easy way to get the caliper off the rotor to pull the front wheel? up until now, i unbolt the caliper and just wiggle it back and forth until it comes free.. but the backside of the caliper always hits the lip of the wheel and has scratched the wheel in the past. it also feels as though the pads are grinding on the edge of the rotor as i torque it out of there. there’s got to be a better way to do this.. am i supposed to pull the pads before sliding the caliper out of the way? what’s your technique?
