I have a weird brake problem that only happens when I turn sharp left going very slow. This turn has to be very sharp (such as in a driveway and not at an intersection). When I turn and apply the brakes it sounds like something is grinding really bad and I can feel it in the brake pedal. Is this possibly the anti-lock brakes kicking in? Brakes feel good at all other speeds/scenarios. All of the pads have plenty of meat on them, new master cyl. less than 5000 miles ago. Any ideas? Thanks
