Reply to "Brake fluid?"

In Panteras, there are 2 other considerations when trying to bleed air from the brakes under vacuum. First, use a couple of turns of teflon pipe-tape on each bleeder screw as you open it, to keep from sucking air in around the bleed screw that's loosened, then right back out. This can drive you nutzo because it may only happen under fairly high vacuum. Brand new bleed screws (or Speed-Bleeders) are coated with something that's supposed to prevent this but it only lasts a few open/close cycles.

Second- especially if the car is stock, the brake warning-light shuttle valve under the booster can get stuck at one end of its travel, mostly but not 100% isolating both fronts OR both rear brakes from the rest of the system. Any air trapped inside tends to stay inside. Unlike almost every other car that uses such a valve, in Panteras there are no return springs inside, so manually returning the shuttle to center is the only option, and its sloppy at best. This is one large reason I discard the assembly entirely.
