Brakes or Wheel Bearings

[BeaSE01]

Looking for help. Not sure if my 09 M45 has brakes that warped or needs wheel bearings. It sits most of the time outside. I sometimes only drive it 10 to 15 miles once every two weeks or so. Once the wheels warm up I get a shudder when I hit the brakes especially if it's a quick stop. I saw there's a TSB which looks relevant but couldn't find a copy of it. Let me know if I missed a sticky on this. Any help would be appreciated.

Welcome to the site.

If it's happening when applying the brakes, it's likely the brakes. You'd be able to hear a bad bearing with the window down and feel it in other situations.

Thanks! It's what I thought too. I'll replace the brakes to get rid of it. Didn't want to do the brakes and find an unpleasant surprise with the bearings.
Any comments on pads and rotors? I saw the Brakemaster recommendation on the sticky's. Just wondering if there's any other opinions out there.

Can't go wrong with those. Had like 4 sets on my old 07 before I got my 2011 and I'm running similar EBay ones on this car with no issues.

If it was wheel bearings, then you'd be able to wiggle the wheel back & forth when jacked up. See Youtube for how-to.
Chances are it's just an out-of-round rotor, which is common among all car brands. See Infiniti TSB ITB00-024f too.
