TR6 broken bleeder on rear brakes tr6

I was attempting to bleed the braking system on my 6 when the passenger side rear bleeder screw decided to snap off. What are my next actions??
 
Left-handed drill bit. Probably best to remove from the car.

Use a bit just a bit larger than the hole in what remains of the bleeder. If you are lucky, it will back the bleeder out at some point.
 
A messy, short-term ("emergency" "get you going again") solution is to undo the hose (or hard line) into the cylinder and bleed as best you can. I've done this successfully when there was no other option, i.e., 10:30 on a Sunday evening!

As noted, you might be able to save the wheel cylinder with a left-hand drill bit or an "Easy-out" extractor. It can't hurt to disassemble the cylinder, put a propane torch on the area around the bleed screw for a minute or two, then try the extractor; this assumes, among other things, that you can easily obtain a proper replacement bleed screw. Of course, unless the cylinder is perfect otherwise, your best bet likely is to replace it.

Should be readily available at your FLAPS. I forget the thread offhand, but it's a standard SAE thread.

While you're looking at replacement bleed screws, you might consider a pair of Speed Bleeders https://www.speedbleeder.com/
Not every place carries them, but my FLAPS had them on the shelf.
 
As a last resort I've bled a wheel cylinder by removing all hardware and one of the the protective rubber boots along with it's metal piston. I then cautiously wiggle the exposed rubber piston cup until a bit of fluid comes out along with the last air bubble.
 
To avoid snapping off the bleeder squirt the visible bleeder threads with a little "PB Blaster" penetrating oil and tap the bleeder screw lightly with a metal tool to get the oil to penetrate the threads. Leave overnight and remove the next day.
 
I was going to suggest EZ Out, but in reality, I had the same issue, and went with replacement
wheel cylinders. I went with the larger rear cylinders from Richard Good. Did it improve stopping,
I don't know, it still stops! I don't autocross, so I'll only know if I have to panic stop, and being of a certain
age, i don't follow very close - unlike most others.
