OK. The truck will last another 10 years, at least. If you are going to keep it that long you might want to hit some things and inspect others while you have these taken apart.

Wheel bearings: wash, inspect and replace if necessary, repack, reseal. You have to take them apart anyway to get the rotors.

Front axle boots: inspect them, time to do this if necessary

Front end: Ball joints, do you hear them clacking when you go over bumps?

Calipers: At this age it is silly not to rebuild them. Seal kit, and pistons if necessary, are best/cheapest at dealer.

My parts strategy is DEALER ONLY unless there are quality alternatives, like the Brembo rotors and Hawk pads, or Timken bearings. Parts store parts are usually more expensive, and lower quality.

I did most of the above over about a two week period and I had to wait for some parts. Sometimes you screw up or find something you overlooked.

Rear brakes are easiest. One shoe kit from the dealer, new drum gaskets and you should be rolling. A shop will mike the drums out for you to make sure they are not too big and that they are still round.
