OK so I think this is coming into focus for me. Given the difference in diameter of the master and calipers, I should not upgrade to the PP calipers at the next brake job without changing both. That is getting into some serious expense that I think I will avoid unless I am having issues. The rotors may get upgraded though. This appears to be one of those things that if you are not on a track you will never notice the difference in performance. The feel will be different but that should be it.

Thanks to everyone who chimed in.
I'd say that sounds about right. Best bet would probably be higher friction pads (maybe EBC Red Stuff/Yellow Stuff) and high carbon rotors (plain faced or slotted; like the Cquence Premium Sport ones I got.)

Sorry for reviving an ancient thread. I'm delving into a front brake upgrade and am switching to the PP calipers in the process. Wanted to chime in for others that may run across this thread to clear up some incorrect information.

The master cylinder change came in MY2013 and applies to both PP and non-PP cars. There is no difference between the PP and non-PP cars. The ONLY brake difference between PP and non-PP cars that I can find are the calipers and pads. All other part numbers are the same when comparing my MKS to a SHO with PP.

I have a set of PP calipers in my possession...

They are literally the same casting as my non-PP calipers. So, there is not even a body difference. The only differences I can see are the pistons and the seals.

Where it gets confusing, as mentioned previously in this thread, is picking the correct brake pads. I think the pads are all interchangeable. The PP cars pads are of a different shape and friction material, but they are riding in the same caliper casting on the same rotors. I'm not sure why Ford chose to change the pad shape. I suspect that they were able to have more contact patch for better clamping force thanks to the better heat handling/dissipation of the improved caliper. But, I don't know why some pads have metal clips riveted to the backside and why some don't.

Here's another style...

Any idea of which style is better? Does it matter which style I pair with the PP calipers? Looking at Rock Auto, there seems to be very, very few that are the top style. Even the pads spec'd for use on the Interceptor Sedans show the pads at the bottom. So confusing. LOL

BTW, thanks to SHO T1M3 for posting pictures of his rusty pads. Wish we knew if they were the ones from the factory.

Anyone have a picture of their factory installed PP pads?

Thanks John but why two part numbers. I found the first number cheaper. The warranty one is more. What's the difference and why would their be a warranty part number as to the other ones for the front

You're asking the wrong person why they list two part numbers and why one is more for the one and the other is dollars more.

The standard one also used the word "economy" next to it. Maybe the warranty pads are the performance package pads? I don't know. All speculation

Yes, im confused as well. I was doing brakes on the wifes sho and ordered some hawk pads. Did alot of research to make sure i got the right ones. Well long story short, the ones i took off looked like your bottom pic (referring to the tabs) and the hawks looked like the top pic. But the hawks were smaller. All this time we thought we had a non pp.....i wondering if we have one now?

Check your sticker in the door....
The door sticker will show you axle code. ...here is the decode:

Axle ratio codes:

1 = 2.77
2 = 3.16
3 = 3.39
4 = 3.07

So, for the PP, the axle code should show "2"

I hate to revive such an old thread but the two different pads shown in the pictures are definitely not interchangeable. The top style is for the 12.8" rotors whereas the bottom are for the 13.8" rotors. I just found this out the hard way when I ordered some Hawk HPS pads for my 2015 non-PP. I received the top style when I guess my car is fitted with the bigger rotors. Hope this helps someone. Looks like I'll be overnighting different pads.

Had to dig this one up bc I am having issues with noisy pads, they are squeaking on decel 20 mph and lower, and yea they've been bedded properly, 3 or 4 times now.

I highlighted these little dimples in blue, I thought these were odd as they make contact with the out edge of the pistons. But the old pads I took off had the same dimples and same indentation from the pistons...

I took the new pads off after a week and noticed the top portion wasn't making contact with the rotor so I ground the dimples off. Now pad makes full contact and I re bedded them. Still same damn squeak.

Does anybody know what is up with the dimples and the contact being made with pistons?

Best guess is that the pads with the dimples spread apart are the outer pads and the pads with the dimples close together are the inner pads.

Great diagram, ty.

The outer clamshell of the caliper has slots for the middle of the pad, the way it's configured now fits the best. I'll take it down again tomorrow and see what I can figure out.

Verified on my car that the outer pads have the dimples farther apart. They don't contact anything, just indicate inner and outer pad.

I swapped right side pads as the left is not making any sounds even though they are installed wrong.

The now outer pad does not have the 2 slots that engage the middle of the outer bracket.

Can clearly see where Pistons were pushing and where I ground the dimples down.

But as I said, the inner pad now has the middle dimples that don't have a home, in which they did when they were on the outside.. so we'll see on drive home.
