If you have access to the failure data check which airlines are experiencing the failure and which are not. If you have access to this data then check to see which of these airlines operate in or near salt water and warm or hot temperatures. There is a possibility that in this case air temperature may not be a factor and that the heat rejected from the brakes is the heat portion of the salt environment / heat equation.
Also if you have access to the data sheet for the grease check to see if the MoS2 is inhibited.

If memory serves me correctly ROYCO is or was a division of shell as their products were listed in the Shell data book.
Speaking of the AEROSHELL book I would strongly advise all of you to contact Shell in London and request a copy of this excellent handbook. It is available in hardcopy and CD. The Address is :
