-Master Cylinder (bench bled twice)
-Both 3/16th lines to the front.
-Both front hoses.
- All 4 wheel cylinders, shoes, springs, drums, self-adjusters
- 5 foot section of line going to the rear hose.
- Rear hose
- Both 3/16th lines going to the rear.

I seem to keep getting air in the system so I installed 4 speed bleeders.
The pedal will start to get firm and just go away.
I can hear the shoes hitting the drums..both front wheels you can hear the shoes dragging the drum very slightly. I never considered adjusting them?
