New guide pins came with the new caliper I've added grease and check the sliding without the pads. The caliper slides nicely however there is a play that caliper has on the pins but I think its normal. The pads that I got on it are from autozone and were originally installed on the other side which works fine, they come in and out easy there is no sign of seazing on the pad side. I am troubled by the abnormal wear pattern on the old pads (diagonal) has anyone ever seen this? I have felt the brake line all the way through and there is no flat spots, abnormal bends, or any signs of defect. The system bleeds fine so the fluid is passing through. However, every time I go for a test drive around the block and pull into the garage and jack the car up the "bad" wheel barely spins while the other one spins just fine.
