Warped Brake Rotors and Steering Shudder/Shimmy/Vibration/Shaking

Look through any BMW message board or forum and you will hundreds of posts regarding recurring front end shimmy/shake/vibration during braking. Now, it is certainly true that older models, particularly the E24 6 series, E21 3 series, and E28 5 series had some issues related to the steering components and bushings, but I would estimate that most posts pertaining to modern BMW shaking or vibrating under braking involve an E36 3 series. Complicating matters is that the E36 cars (minus pre 6/92 build date cars and M3 models) are notorious for ball joint, control arm, and tie rod issues that make diagnosing and eliminating front end problems tricky. My 1995 325is has been experiencing progressively worse shudder under braking - and not just at speed where front end shimmy typically manifests itself. I replaced the control arm bushings a year ago, and all ball joints earlier this year. I happened to have a new set of tie rods lying around, but replacing the tie rods did not solve the problem either. Most people I spoke to felt my brake rotors, less than 1 year old and never abused or saw anything other than commuting and regular street driving, were warped. This did not make sense. How could modern steel rotors warp so quickly with seemingly no abuse? It turns out the brake pads themselves are the culprits 99% of the time. Melted brake pad deposits build up on brake rotors, and the solution is to change out the pads in favor of brake pads with a higher heat range. Rob at UUC recommends "Akebono Ceramic or Hawk Performance Ceramic. You won't get pad deposit from either of these, and as a side-benefit they have very low dust. New pads should remove the deposit, so you don't even need new rotors right away. A couple of days and your shimmy should be gone."
