2007 Tahoe codes c0267 & u0073 traction & brake light come off and on while driv

What is your question?

I have a 2008 Tahoe and the traction and brake light come off and on while driving. If I have my vehicle on cruise control when the brake light comes it it disengages my cruise control. There is also a grinding noise in the front tire area when I take off from a complete stop. I was given the codes u0073 and c0267. What exactly do these mean and what repairs do I need done. I don't want to be overcharged for something I don't need.

What makes this problem better or worse?

Not sure what triggers it.

How long has your 2007 Chevrolet Tahoe had this problem?
