New brake pads installed. Right front caliper was a rusty hulk and completely seized up solid. Once I hammered the brake pads out, the pistons slid back in the caliper like nothing was wrong, I suspect the pads were in a bind in the caliper, not the pistons sticking in their bores. With the new pads installed, no brakes dragging, no squealing, and no more idiot light on the dash! Fingers crossed there's a reduction in brake dust, the Textar pads that were on there were just obscene.
