Hey Scotty,
I have a 2014 Nissan Quest 156,000 miles. About a 1.5-2 years ago I noticed my drivers side front caliper needed to be replaced. So I replaced both front calipers and new pads and rotors. I was good for a while. Until I noticed the steering wheel shaking intermittently when I press on the brakes on the freeway. When I look at the brakes I noticed my passenger front pads and rotor wearing down much faster than the drivers side. I seem to be replacing pads and rotors every 6 months with only the passenger side being worn down. I bought the calipers, pad and rotors from O'Reilly's. I have tried different name brand rotors and pads but get the same outcome. Is it possible that the passenger front caliper is my problem even though it is probably less than 2 years old? Is there anything else I need to be looking for as the cause of this problem. Thanks for all your help!
Check front end components and wheel bearings.
