I made a huge mistake while changing rear pads. I got in a hurry and spun the caliper piston out instead of in on the rear passenger side. Some fluid leaked out but I got the piston turned back into the caliper. The brake pedal is very spongey, any advice on bleeding the brakes would be greatly appreciated. The ABS system warning light is not lit. And the brakes seam to be working very well, minus the spongey pedal. Thanks.
