Certain de-icing fluids can harm carbon brake disks. The fluid can soften the carbon and lead to premature failure. Under certain circumstances, you may need to clean and inspect the brakes after exposure. For more information visit www.faa.gov and read FAA Special Airworthiness Bulletin NM-08-27R1, or contact your aircraft OEM.  Be sure to check your aircraft maintenance manual for precautions when washing as well.
