My apologies if this has been covered, I did search before posting.
I just had another brake caliper (RF) freeze up on my 05 F250 diesel. 75485 miles. The first one (LR) was at about 68000 miles. Are there any aftermarket calipers with stainless pistons? Any thoughts anyone. Thanks. David.

 

I don't know of any off hand, but back when the GM 4 pistons first came out there was alot of seizing and a number of brake companies would reman them to add stainless sleeves to them. I'm sure there's someone probably modifying them. Good luck.

 

I don't know about any stainless replacements, but both my rear calipers froze up at 38k miles.
