It's probably a no-brainer, but discolored brake fluid in the rear barrel of dual master is not a good sign. The fluid is full, but color is off - like someone stirred in a little cocoa. I also hear a little chirp coming from rear brake. Sound familiar? Wisdom and experience welcomed.

What's been changed from all appearances:
1. Drums and shoes
2. Dual master (not sure when)
3. Power booster (not sure when)
4. Brake lines
Note: overall restored vehicle sometime in last 10 years.

I haven't pulled rear wheels lately, but as I recall, the wheel cylinders looked older than all other brake parts. Especially in rear.

I'm looking forward to the day when I can just drive this doggone truck. Ya know what I mean?
