Brake rotor stuck

[mmullins1975]

What would cause the brake rotor not to turn when installing an new caliper and pads? But if I use the old caliper and the new pads the rotor turns freely.

thanks

The caliper is too tight. That can be caused by the caliper not releasing pressure or some other flaw in it.

I'm sure you've fully collapsed piston(s) on the caliper. Also could be a mounting hardware issue, not allowing the caliper to locate properly.

If the old caliper works with new pads.... There's something odd about the new caliper.

Did the new caliper (with new pads) slide over the rotor during assembly without problems?

Odd situation. How did you manage to get the new pads/caliper onto the rotor when it's so tight the rotor won't turn? Or is it a matter that once installed and you apply pressure to the brakes, the caliper won't release?

If it's a matter of not releasing, you might have to run some sandpaper on the areas where the metal slides (been some years since I've dived into one of those)

My thoughts too.

If you open the bleeder screw, does that free it up? If so, then check that brake hose.
