At 19500 km I got them fixed under warranty (only took an hour or so to machine the rotors). The dealer gave me a really hard time, claiming the warping was due to lack of maintenance (not true, in my opinion). Anyway, I am at a loss to determine a cause. The dealer (other than being sure I was the cause) was not able to offer any explanation. The brakes were not overheated, seized, or anything else. I suspect (hope?) that there was some stress in the original casting that caused them to warp spontaneously. I also hope that this spontaneous warping has now ceased. If the warping has not ceased, and this is a common Honda defect, I would like to hear from others so that I can prepare my case when my brakes warp again in a couple of months. Aside: I also have a '76 Honda. The calipers on this car regularly seize due to rust. This wears out the pads instantaneously and has, on occasion scored the rotor quite badly. But the rotor has never warped, and I have never had it machined.
