Hey Hoyt, Don't jump on me too hard, I've only met you face-to-face once and been on the list for 5 years, but... did you measure the inside of the AL caliper body and the outside diameter of the piston? You mentioned that the seal was new, but I'm wondering if still some minuscule amount of fluid is weeping past the seal and is attracting moisture, which in turn is creating all the crud between the AL housing and the puck. If the measurements are out of whack, you may have to make a *slightly* (I'll let you the machinist decide how many thousands the increase needs to be...) larger SS piston. Just a thought from a "newbie"...
Glad to see you back on the list my friend!
