Which by the way the 12.44 is 5% longer than the large 11.75 brake and 18% longer then the stock 10.5 brake. Thats alot more leverage.
 Totally. The larger diameter means a LOT more leverage. Think about bicycles, two small, soft little pads worked wonders on a thin ribbon of steel that happened to be REALLY large in diameter compared to overall diameter of the wheel.

I haven't checked so I could be totally wrong but I've heard pads are hard to come by for the K/H brakes, which means upgraded compounds probably don't exist... Where as the Bendix floating caliper type there are performance pads and the 11.75 rotor upgrade is an easy bolt on...

I haven't checked what is available, but since the pads are the same as 65-67 Mustangs, there should be some options............

Just checked the local o'reilleys and they have pads for the KH at $10.44 in stock and that is the only one they have availble "premium organic". They don't have any in stock at the store or warehouse for the single piston but there are several choices they can order from $11.39 up to $32.08 for semi metalic.

Town Car: 4,006–4,369 pounds (1,817–1,982 kg)[17][18]
Town Car L: 4,360–4,517 pounds (1,978–2,049 kg)[19][20
Crown Vics were a little lighter, at about 4100 - 4300 lb. Most cop cars carry around at a minimum, 500 lb of gear if not more. So I'm sure the designers of the CV police cars had brakes for panic stopping from high speeds with vehicle weight of 5000 lb. plus.

I have disliked the KH 4 piston calipers since the late 70's. They were always a major pain to rebuild and not have them blow. 
Yeah, on paper they are fine, but, back in the day, when I put 30-40K a year on them, I was lucky to get 6 months without a stuck piston. Silicone fluid helped, but there seemed to be no real fix. I regularly bought new ones at the dealer and rebuilt some of the old ones.
4-piston is generally thought of as "best", but the K-H's were just trouble. The Bendix (B-body), Budd (C-body), and all the later stuff is fine.
Plus, the K-Hs used tiny pads, thin rotors, etc.
Leave 'em for the platinum-resto guys!
