Uh ofcourse Boeing does. It's been ticked on the option list before they were made I presume. We're not the only airline with carbon brakes on the NG's either.
Carbon brakes can be kept for more cycles and so keep cost down for replacing them since they fade less quick than steel brakes. (if the correct braking technique is applied).
(thread creep) back to the original thread....: never experienced a shudder like that on our NG's, only when the antiskid activates as Old Smokey said before. Interesting one
