I still don't believe the fluid will pull the pistons back, the master would have to be way below the caliper and the lines would need to be much bigger. It's more likely the rear brakes are not adjusted up correctly. With a master cylinders on the firewall, just how much fluid pressure do you think there is pushing through a 3/16" steel line on a caliper seal? It barely bleeds out with the line open.
Originally, the drums all worked correctly, why would disk brakes be any different?
I'm just asking, not trying to offend anyone, I just keep hear the same things over and over on multiple web sites with out any proof its correct.
Bet if you actually measure the fluid hight in the master and front caliper, bet theres hardly any difference, more likely the master is above the caliper slightly.
