Heavy duty brakes

I have a call in to Parker, will advise on what they say.

From what I see in your picture it looks about right. If you finish putting the caliper together and see what you get if the pistons are coming out 1/4 inch something is wrong. I maintained 6 with heavy duty brakes and for the pistons to come out 1/4 inch the pads and disc had to be worn out with new disc and pads the pistons were flush in the housings.
Make sure when you get them back together that the calipers are free to move and not binding and your wheel spins freely

All back together about .080-.090 of clearance that the pistons have to take up rotors are just a few thou below new and pads about 10 thou below new.

Still waiting on Parker, I still think that is a lot for the pistons to come out compared to other comparable installations.

Well, I've never done 6, but I have done 1 for 27 years, (or 27 for 1 year, your choice.)
I agree with your post.
The pucks on mine, with the calipers loose, able to float, are trouble free, regardless of the distance, (I never really gave it much of a thought, since they are pretty deep to the oring, and looked identical to what I saw coming off)
I doubt Parker will give an answer, at least one that is specific...

Talking with Parker, with all new parts, pistons will be out of housing .020-.040.
The 07 disc today is the same as the original disc that was welded, new part disc thickness is .365, with a minimum wear down to .330.

All back together works fine
