I’ve been working on changing my brake pads today. I removed the lug nuts with cross pattern wrench and was able to reinstall them. I tired using my torque wrench to tighten them to the specified limit. When I use the 7/8 socket, it slips. The 13/16 doesn’t really fit well, but on the cross wrench I used the 13/16.

I have a 06 Mustang GT. Am I using the wrong size or do I need to replace them?
