I just had to put new brakes on my '99. Two calipers both passenger side had on piston stuck in each caliper and one rusted tight lower slide pin in each. The rear was the worst, it had the pad worn at a severe angle. The calipers were not centering (rusted pins) and one piston did not work at all, one probably was moving out but not releasing properly. I changed all four calipers and pads.
Just had to pop the pistons out again and clean them up. replaced the pads and we are ready for another 10,000 miles until next time..

I had a problem with the rear brakes, too:
On the driver's side, the slides were seized up and I had an uneven wear on the pads: The inner one was gone, the outer one nearly new. On the passenger side, on pad was worn parallel, while the second one was wedged by 1/8 of an inch!.
Finally, the caliper on the driver's side failed.
I replaced everything: calipers, rotors, pads.
But: I have AFTER the replacement dragging brakes, I can notice it in the fuel consumption. When I replaced the rear brakes, I also flushed the brake system and filled is with new fluid. The front brakes got replaced about 6000 km ago.
Any ideas?
Thank you
yes when the rear brakes drag you will notice the truck working harder with out of sight egt's. Along with using a lot more fuel then normal.
One item not mentioned here is that it is recommended to flush the brake system every 3 years. As mentioned, brake fluid is hydroscopic thus the moisture on the pistons. That didn't come from a leak unless you off road it in streams. Look at the color of the fluid in the reservoir. I would almost be willing to bet that 90% of the problem brakes have never had the fluid flushed as a maint. item unless new brakes were being installed. and probably only about 1/2 of them.

I'm going to through a SWAG here as I've been out of the game for a year now and don't get any reports on issues.
I think the rust is forming between the O-Ring and dust boot, and that the dust boot is allowing some humidity / moisture past it's sealing surfaces.
I am with you. I do not buy the water absorption into brake fluid causing rust. Certainly not in my case. Built 6/06. I bought it in Jan 07. Every car on the road would have the same issue. It may happen but not to that extent on the INSIDE of the hydraulic system

no one said the brake fluid was the major cause of these failures. It was meant to point out another contributing factor whose recommended maint. is probably neglected by at least 50%, probably more, of the owners out there.

Well every car on the road does have this problem. Not bleeding the system regularly ain't a good thing. Next time you replace a caliper or cylinder take it apart and see what you see.

I have never had a caliper fail that way. Not to say that it does not happen. I have just never experienced it. Then again this is only the second truck that I have had rear disc brakes on.
I know that they do rust just not in the frame of time that I gave in a sufficient amount to cause it to fail. I never said that it did not or would not happen just hard to believe after 2.5 years on the road.
I think the more probable idea is a failure of the seals that are supposed to protect the piston and slide pins. Of course some testing would be required to prove that..... as for now nothing but speculation based on my own experience, intelligence, and common sense.

Time to throw in the towel son. Your just digging a deeper hole for yourself.
Really? Whatever man. Keep thinking that in the mean time I'm gonna watch that Yanks spank the Angels. I am not quite sure you actually read my post but I really don't care to engage in an argument with you over what you THINK might be happening

This is why I refrain for trying to help anyone in a 6.0 forum.
No experience versus allot of experience. You couldn't buy a clue if you won the lottery!
Ok let me explain it another way so you understand. My idea is supported by an observation since rust was found on the OUTSIDE not internal to the system where it is in contact with the brake fluid. Of course if I am right you MUST be wrong. No challenge there dude, relax, have a beer and watch the game.
