I could be wrong but it was my understanding that Teflon tape was not to be used with DOT 3 etc brake fluid...

Teflon is the most chemical resistant stuff out there: brake fluid won't hurt it. I think the issue is that brake flare connections are supposed to install with no sealant at all, as are brake hose connections with straight thread that seal via crush washer.

In that vein, the bleeder holes aren't supposed to seal by the threads, they seal by the base of the bleeder. Plugging those with Allen screws (even with some sort of thread sealant on there) definitely ain't the right way to do it.

Can't you just put proper bleeder screws in those holes? I would think that would seal fine, no thread sealant required.

I'll add that it seems really odd you lost brakes completely. With a dual-circuit system you should've still had fluid in the rear part of the reservoir, and the rear brakes still should've worked. You also should've gotten a brake warning light on the dash.

I think after you fix the caliper problem you should go through and make sure you don't have something else going on as well.

Got it, I thought you were putting teflon on the plugs that replaced the bleeders that should've been there.

The leak was definitely from the 5mm plugs on both calipers. I checked all other areas of the brake system for leaks and nothing was wet. As mentioned, the master cylinder was empty and when I pressed the brake pedal rolling backwards down my driveway, the pedal went to the floor and there wasn't anything.

This is the '86 listed in your sig? The MC reservoir should have a divider about halfway up such that even if you lose all the fluid out the front, the rear reservoir will still be half full and your rear brakes will function.

Or are we talking about some older car with single-circuit brakes?

It doesn't seem right that you lost all brakes on an '86. The front and rear should be separate circuits. You also should've gotten a brake warning light from the float in the reservoir.

Regardless of what you do with the Wilwoods I'd suggest investigating further.
