braking vibration

[buff51p1]

I have a 1999 I-30 and I replaced the front brake pads about 2 yrs ago about the last 3 months We get a vibration like you get on a washboard road when you come to slow stop. The biggest problem is it doesn't do it all the time only occasionally. I was wondering if it could be the rotors I did not have them turned when I changed the pads everything looked good. Does anywone have any ideas on what might be the cause?thanksBuford

I get that symptom on my Dodge when the disc pads cracks in half from heat.

You probably just need to get the rotors turned.
