[Oh Haha]

Our Grand Caravan has 43,000 miles(we bought it with 36,500). While we were in the UP the brakes started shuddering with application.

My wife drives the van to work, about 400 miles a week but I was driving during our vacation. It was very noticeable on a freeway offramp, slowing down gradually from 70 MPH.

I pulled the front rotors today and had them turned and it's back to normal.

My question is what causes the rotors to warp? I know that hard use like on the track can certainly be a cause but what about the family truckster?

When I come to a stop after gradual slowing I will release the brake pedal for a moment and then gently hold the vehicle still. My thought is to not "melt" the pads into the rotor in one spot. I do this with every vehicle I drive including my work trucks, with and without air brakes.

What is the general thought on warpage?

BTW-my sister has the same problem in that she only gets around 10,000 or so miles on a set of rotors. Is it the driving style of the gals?
