Steel Line or Wheel Cylinder?

[lbpd719]

well, I am finally getting to the heart of my disappearing brake fluid problem on the 72 240z. Looking at the back tire I could see some residue on the back side of the drivers side rear wheel.

It's been several (over 12) years since I have worked on Drum brakes. The rubber line still appears nice and dry. I pulled the drum off and found the shoes and inside of the drum nice and soaked in brake fluid.

Anyway, I would still like to confirm with the community, I have a blown wheel cylinder. I had a similar problem in the late 80's (ugh) which turned out to be the steel line on the backing plate.. I can't remember if that leak made it all the way into the drum though.. Anyone agree or disagree?

Thanks in advance for your time..

If it is still too hard to determine what the problem is, give everything a good wash down with a degreaser to remove all the crud.

Then pump your pedal and see where the fresh fluid appears from:classic:
