Air Brake Chambers - Jack Houpe - 10-05-2026

I'm replacing all my air brake chambers along with new seals and slide pins on the Rockwell Meritor air disk brakes. I founds 2 chambers on the tag axle which I read the date code (AI did) and they are 1993 and that scared me, the drive axle is 2012 and 2013, the front steer chambers where the same as the drive axle. 

What is everyone else doing as far as time?  AI says 5-7 years or 500k miles.
