Sorry, I missed that your whole post had an "old cert rules" qualifier in the second para.
The new rules require worn-to-limit brakes (or a correction to that state). As to the old regs ... wait one.
OK, the max KE demo with 90% worn brakes came in with Amdt 25-92 in 1998. Prior to that the Accel-Stop para (25.109) had NO max KE requirement. (Though other paras may have applied, at least in part - 25.1301 "performs its intended function" comes immediately to mind as one candidate para)
The fully worn requirement is actually 25.101(i) and also came in with Amdt 25-92. Again, one could have argued about other regs. But there's nothing explicit.
