changing my rotors and broke a parking brake

Hello, I'm Danny.

Sorry, Your pictures didn't upload. Having a broken pad would cause damage! You don't want to have parts rolling around inside the disc causing more damage. You definitely need to fix to prevent major damage/loss of complete brake system. Here is a tutorial showing how to replace:

Thanks for your swift reply/answer very helpful.

Hello again.

As I stated, having that pad crumble/disintegrate will cause damage ! I suggest fixing before having it causes major damage. Let me know if you have any other questions about this. Hope this helps and thanks again for using 2CarPros.
