A brake pedal that pulsates under the foot while braking the vehicle has been noted by many owners of the Honda Odyssey. This issue spans many years, and multiple generations of the well-known minivan, and Honda has taken measures to correct concerns. The front brake rotors are the cause of the break pulsation, and are subject to a condition known as lateral run-out, or simply called warped brake rotors. As the brakes are used, heat builds quickly in the brake rotors and brake pads, as a normal byproduct of friction. This heat can become too great for the original rotors, and cause the metal to warp over time. Once the rotor begins to warp, the warping process accelerates due to uneven heating of the brake rotor, and the issue will quickly turn from light pulsing of the pedal to full-vehicle vibration. Revised brake rotors have been released by Honda, and will correct the concern. The brake pads will need to be changed at the same time. Note: this error has been known as early as 20,000 miles.
