How dependant are our brakes on wheel torque?

Few months ago, I threw on new pads and rotors all around. All was well.

Last week, I took my car to a nationwide tire shop for new tires. About a day goes by and, everytime I brake, some god-awful 'crunching/scraping' noise is emmited from somewhere. It got progressively worse until today, when I had time to look at it. First of all, my torque wrench goes up to 180 lbs. The wheels were torqued well beyond 180 lbs. After I got the fuckin wheels off, the pads, all around, were glazed and scored nicely. I put, again, new pads and rotors on all fours, PROPERLY torqued the wheels, and all is well again. Is it just a fluke? Or did the 8,000 pounds of torque on the wheels fuck everything up?

Over torquing the wheels isn't good for the brakes...and yes on some cars can damage the rotors I believe. Looks like that's what happened to you.

 

That shop probably used an impact to torque them....the shop will tell you that it won't over torque, but obviusly did
