said... The drill pattern has to be carefully
done as the holes will increase the thermally-induced stress in the rotor and
the drill pattern is usually designed to expose every part of the pad to a hole
at least once per revolution. For an aircraft that only has to stop once,
the best approach might be to use metallic or semi-met pad material and not
drill the rotors.
Gary, great input. The hole pattern will allow all but the most inner edge
and most outer edge of the brake pad to be exposed to a hole 12 times per
revolution. The limitation of hole spacing on the most outer and most
inner edges was to maintain "hole edge distance". The slots were added to expose
the most outer and most inner edges 6 times per revolution. This is very similar
to the approach Baer Brakes use. The new IV-P pads have pretty high metallic
content. My intuition said they would work well with the drilled holes. Your
further input is desired.
