Most OEM dually brakes will last forever. Make sure to go back with OEM. I have 205k and original rears. Feeling guilty so I’m changing them.

Brake fluid attracts moisture. 24 yo wheel cylinders belong in the trash would be a good starting point.

Is this a FFFFord V10 dually or a Dodge V10 dually? I don't know squat about a FFFFord but on the late 90s Dodge duallys with rear drum brakes we used to swap the rear wheel cylinders to chevrolet or gmc duallie wheel cylinders because they had a larger diameter piston than the Dodge wheel cylinders. Braking was vastly improved and it was a bolt in swap.

Didn't most of those have a brake proportioning valve over the rear suspension that compensated for the amount of weight over the axle (due to squat)? Suppose that has failed?

We had problems with that on GM dualies in past!
