Ed: Thanks. I have never heard of this before on other cars. I would guess if the internal seal goes beyond the normal position in the master cylinder, the cylinder may not be "polished" from use and may therefore be rough enough to tear the seal, or, the seal is somehow is allowed to go beyond the cylinder's length which I would find surprising.

I finally got around to replacing (vs. rebuilding) the rear calipers on my '89 3.2. Now on to bleeding - I bought the Motive pressure bleeder, filled, connected, & pressurized it. Brake fluid promptly leaked out of an overflow tube from under the left front of the car. Nowhere in the directions or on any of the posts does it mention this. I've heard that you may have to pinch off the overflow line? Help is appreciated! Thanks, Greg
