Ok, what is the deal?

Rotors were warped so I got new pads and had rotors turned by Pep Boys in February 04. Needed new pads anyway.

Then, in May, the rotors started warping again. Took it back to Pep Boys and they said that the thickness was not enough to turn the rotors. So, since my 92 Accord has the old design, the cost of replacing the rotors was about $240.

So, got new rotors and the existing pads. Raybestos Rotors and Raybestos Ceramic pads.

Now, it's July and guess what...rotors warped again!! I have never in my life had rotor issues with any of my Honda's! What is the deal? Here is what I am thinking may be going on.

1. I have 15" aftermarket wheels that are a very "open" 10 spoke design that allows alot of water into the brakes. The factory wheels pretty much cover the whole disc area and probably allows less water to get in, but they were bent and needed new ones. I don't know why an open style wheel would cause an issue but, you never know.

2. I don't use my brakes often. Since 95% of my commute is on the interstate, the brakes are used mainly to come off the off ramps and slowing down from highway speed. Is this prematurely wearing them out?

What else besides the rotors could cause front end shake when slowing down using the brakes? Tires are balanced, alignment is good and when the rotors were first replaced, no issues for about 3 weeks. Are ceramic pads causing an issue? I used ceramic because of the limited dusting.

Does anyone have a clue or have similar experiences??? Thanks!!
