I have an issue. I just recently noticed that when driving at speeds of 50-80 mph and when I brake I get a vibration shaking in the front end. I was told by Advance Auto my brakes and rotors are fine and Firestone says without looking that my rotors they are warped. I do not know who to believe. The guy trying to save me money or the one trying to take my money. It only happens at high speeds. I drive locally it seems to be fine, but when I come to a stop I can actually hear some kind of rubbing with the brakes.

Usually that is caused by front rotors being warped. Can you feel it in the steering wheel at all? Have the brakes been inspected?

Somewhat feel in steering and sometimes it feels to pull a little. I have not really had the brakes looked at, but just had tires re-balanced and rotated. Two of them were out of balance. I getting ready to take a ride on freeway to see if that helped any.

An out of balance tire will not cause a vibration while braking. More than likely your front rotors are warped.

Sometimes a auto parts store isn't the best place to get advice. It will vary from employee to employee some good some bad.
