Working my way through the 3100 getting it back on the road again.
Pulled all the drums last night and was surprised to see all but the right rear trailling shoe were all still very serviceable. The trailing shoe on the right rear is the only one that is worn down more than the others but still has alittle life left. Atleast enough to get it roadable.

The front bearings are different from any I've seen before. The ball bearings are big!
They too look very serviceable and I'm just going to clean and repack them.
The truck has been parked in the dry since 69 so overall brake component condition is unknown other than they no-workie.
There is no pedal at all.

I am pondering 2 points of attack and am looking for opinions.

1) fill the MS w/new fluid and pump away to see what happens.

2) disconnect all lines at MS and WS's then blow them out 1st then reconnect and try to pump them up.

what say yee?
