I can release parking brake with button, but the emergency brake won't release.
Locks rear wheels to barely tur. Ideas please?

If the rear rotors were just replaced then likely the rear venting clearance was not set correctly.
Another common failure after brake work in the flex hoses to each suspension. They get old and collapse internally and can hold brake fluid under pressure in the caliper.

You have to pull a pin out so you can take the spring out. Then you can get a feeler gauge in between the pad and the rotor to adjust the clearance.

Try opening the bleeders on one of the stuck calipers. If it releases, replace the flexible brake lines. BTDT.
Otherwise double check the venting clearance.
