Hi Folks, hope one of you can help me. My rear brake pulsates when I'm stopping. I've checked the disc and it seems to be straight, couldn't get it off the wheel as the bolts are solid. The bike is only 2 years old !! I've changed the pads, albeit for the same make / specification and it still plays up. As I slow down for traffic lights or use the rear brake for slow manoeuvring off road it's like the brake is grabbing and letting go, then grabbing again. And no, I don't have ABS. Thoughts please chaps.
