Tires not turning in neutral
i changed the front pads on our 2004 and noticed there seemed like resistance up front. Car wouldn't even move with foot off of gas. Jacked it up and could barely turn one tire and couldn't turn the other while in neutral. Thought maybe the caliper piston wasn't retracting, but they didn't have any in stock until tomorrow. So I took it apart again and cleaned and lubed below and above the hardware. The pads fit good, practically fell out of place. This time the opposite wheel turned but not the other, but the car did move with foot off the gas. Any ideas? Should I still replace the calipers? (2004, 4 cyl.)

The brakes were OK prior to the pad change?
Did you check for free play of the caliper at the slider pins? The caliper slides in and out on two pins. This to allow for compensation in pad wear.
The pads will always drag on the rotors and cause some resistance to tire rotation. However, if trans in neutral the tires should be able to rotate easily enough by hand.
With caliper and pads fully installed on car. Did you try to observe any pad movement when pressing on the brake? When the pads were off, did you try to retract the piston using a C-clamp, etc.
This to check for a frozen piston. Then with piston now retracted and brake reassembled, check for free rotation of the axle hub.
The pads should be retained by clips. This typically requires the pads to be pushed out of the caliper. Since the pads feel out the clips in place. Is it possible the pads are getting skewed in the caliper?

The brakes weren't that good before the pad change. Tried to clean things up, slide pins were rusted bad and one piston looked asymmetrical. Replaced the calipers and it's better, but not great. Will rebleed the brakes again to make sure. Thanks for the help.
