Hey all, have been noticing an issue of late when slowing to a stop using the front brake (20km/h and under) I'm feeling a fair amount of pulsing up front. As if the pads disengaging for a section of the rotor and then grabbing again. I've had warped rotors and it feels similar to that but only happens when I'm going slow. Bike only has 2600kms on it, so was dubious if rotors would warp so early in the price. Any advice would be gravely appreciated.
