My 2001 Grand Cherokee had 3 different calipers lock up at different times. Also had to replace a rusted out brake line. The third time it locked up I sold it to the mechanic.Brake fluid should be changed when it's bad....You can buy a brake fluid tester for under $10. It measures the moisture content of the fluid. Useful life of the fluid will vary.

My '91 F-150 had a caliper lock up on me a few years ago. I bought the rebuild kit, saw some corrosion and gunk in the piston bore that caused the bind. I know I replaced the brake fluid at some time before that during the past 31 years!
And my '01 XJ had a dragging caliper, it had been replaced a few years before. Found a torn dust seal on that one which let crap in.
While corrosion on the inside of the system can lead to problems, a bigger problem is the outside of steel brake lines rusting and causing leaks. Had to replace the lines on my XJ before it was 15 years old.
It's a Jeep thing!
