I'd do the wheel cylinders, I'm doin ALL of my brakes and bearings right now, most of the wheel cylinders had a small leak...

Have you already replaced the shoes/had it apart? Because it is such a pain to disassemble, many people never do the rear brakes on these trucks (mine appeared to be one). Metal to metal doesn't give much friction.

The best mod I did to mine after rebuilding the brakes was to install a used power booster (manual before). Stops great now.

i replaced everything wheel cylinders and all... you are right looks like they didn't want to touch the rears the parking brake lever was also hangin all good now

I'm gettin ready to re assemble everything right now.

I'm surprised how little fluid was left in the lines O:

I think the ol truck will stop pretty good, There's quite a bit of surface area for these drums to start slowin the roll.
