I changed the pads and rotor this weekend. Now I get a vibration between 10 and 20mph. If I push on the brakes it stops. It doesn't do it all the time. I checked the lug nuts and the caliper bolts and they were tight. Any thoughts on what could be the problem?

 

warped rotors would be my guess or the rotors are not true.

 

+1 search or the rotors aren't completely onto the hub, re-torque the lugs drive 10 miles then re-torque again.

 

try getting then turned that might fix it

 

The rotors are new I replaced them with the pads. If feels like its coming from the drivers side. Could the caliper be sticking a little. Would that cause it?
Yesterday I drive 60 miles no problem. On my way home It started acting up. I today I pull off front tires recheck everything and it was fine. Drove 20 miles and it was fine. Did some running around town and it started up again.
If I'm on the brakes till I stop it doesn't do it. If I use the brake enough to come to a gradual stop then it does it.

 

Pull the wheels and look for a spot where a wheel weight was,just to see if one came off during the brake job....What brand of rotors and pads did you buy for it? Were they remans or new? You'de be surprised at how many mechanics can tell you of new or reman rotors that weren't true,I've even seen them overturned and too thin meet minimum req's....just to eliminate you could rotate your wheels front to back and see if it goes away...kinda isolate to or away from the wheels/tires.....

 

I bought the pads and rotors at autozone. duralast pads I can't remember the rotors they might be the same. Another thing I noticed. I have a little play when I move the tires front to back. I'd say less than 1/8 inch. I don't know if that would have anything to do with it. I wouldn't think so since I never had problems before I did the work this weekend.

 

hmmm... wheel bearing? jack it up in the air and turn it by hand... does it grate?

 

could be a wheel bearing,try what srch suggested...I bought A/Z rotors for my van and one wasn't true,no probs returning it...That's why I asked,I was wondering if you bought yours from them also....

 

it doesn't hurt to get your rotors turned or checked at least
