Default Pulsing noise when I brake.

When I brake decently firmly my passenger side rear wheel makes like a pulsing noise, like and intermittent rubbing noise. Does anybody have any clue what this could be? Bad hub? How could it have happened? Any info would be appreciated!

Very strange - You are lowered, yes? Do you have any rub marks on the tire or the fenderwell? Any other symptoms?

Yea, lowered, rub marks was the first thing I checked, not contact anywhere, tires sidewall wasn't abnormally warm either. All my suspension components aren't showing and marks of shifting (I was looking for clean areas around the bushings to show if they had been there previously). I'm thinking maybe my rotor is warped or i have a bad hub back there, but I don't see how either could have happened, especially the rotor warping!

You have decent A/M rotors, but they still could be warped if you had a high-speed weekend. Have somebody watch your rear-wheel as you roll along and look for a wobbling wheel. Next, get it up to speed (30 MPH) and have someone watch the rear wheel as you hit the brakes. Sometimes this has shocking results! I would help you out if I was in OK and then we could get a beer, but I am a bit farther east...

I'll see if I can have someone look at it, it just really hard for me to believe i warped a REAR rotor, I haven't had any hard braking etc., maybe the lugs aren't torqued properly. Thanks for the help!!! If anyone else has input I'd appreciate it also!

You may have a rear caliper hangin' up. Good luck and let us know what unfolds.

Reza, if it doesn't get nasty this weekend like the weather man has been saying, we can check to see if you have any wobbling or something of the sort.

Sounds like a warped rotor.

Would a brand new rotor do that? He just put them on last week. Or could he have it just a little bit off or something?

I have a hard time believing its the rotor, I'm a lil worried its maybe an axle bearing because I had to tap the stock rotor to get it off from being rusted on. We I'm gonna swap it back out to my stock rotors and see if it makes any difference, if so I'll have the new ones resurfaced. I guess I could have warped them by mis-torquing the lugs. Any opinions on the axle bearing thing?
