Need help, what should I be looking for

[jknight8907]

I've got a 2007 Sierra 2500 with the Duramax home from the dealer for the weekend to try out. It's got 66k miles and seems to run great. The only possible issue I see is the brake pedal has an odd vibration in it. Even when stopped, there's a 'buzz' in the pedal that kinda makes your foot tingle. Is this just vibration from the engine or what? What other key things should I be looking at to make sure it's good?

thanks

Never heard of that before could be a ABS issue. Call the dealer and tell them you want the service history print out it will have everything the truck was brought into service for. Look for anything odd especially anything about the brakes. Thats it really check it over REALLY good for any leaks. The Trans cooler and power steering lines are known to leak. Check the top side rear of the tcase for any oil. Don't worry about any oil from the intercooler lines that is normal.
