Kia Troubleshooting Questions? Ask a Mechanic
Hello I will help you with your question,
If it is springing back it is hung up on the park brake shoes. There is a rubber plug in the rotor between the lug studs, remove the plug and rotate the rotor so you can see the notched adjuster for the shoes through the hole. Turn the adjuster all the way so the shoes are loose and it should slide off.
Let me know if that is clear
